Debian :: Fix GRUB After Windows Installation On UEFI System

Jul 29, 2015

My computer's recent history in chronological order:

1. debian jessie is installed using netinstall iso to sda.
2. windows 8.1 is installed to sdc.

Now "lsblk" returns:

Code: Select allNAME                  MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
sda                     8:0    0 111.8G  0 disk 
├─sda1                  8:1    0   512M  0 part  /boot/efi
├─sda2                  8:2    0   244M  0 part  /boot
└─sda3                  8:3    0 111.1G  0 part 
  └─sda3_crypt        254:0    0 111.1G  0 crypt
   
[code]....

Result: My computer boots directly to Windows 8.1. If I press F7 during first seconds of boot and choose "debian" as the boot device (via blue bios screen, not grub), debian boots.

My purpose:

1. To use debian grub screen to choose between debian and Windows. (To avoid pressing F7 during boot to use debian)
2. Set debian as default OS in grub and boot to debian unless I choose otherwise in for example 10 seconds.

I guess that I should update grub to fix this but I don't want to take risk.

Debian Installation :: UEFI GRUB Broken - Dual Boot 7.7 And Win 8.1

Dec 23, 2014

My Toshiba Satellite C870-198 has Debian 7.7 installed in UEFI mode alongside Windows 8.1. The GRUB menu no longer displays, but the machine boots straight into Windows.

I can boot into Debian or Windows from rEFInd installed on a USB stick. The rEFInd menu has the following entries:

The Debian entry actually launches the GRUB menu which was installed with Debian.

Code: Select allBoot Microsoft EFI boot (Boot Repair backup) from Basic data partition.
Boot supposed Microsoft EFI boot (probably GRUB) from Basic data partition.
Boot EFIubuntugrubx64.efi from Basic data partition.
Boot EFIdebiangrubx64.efi from Basic data partition.
Boot bootootx64.efi from Basic data partition.
Boot vmlinuz-3.2.0-4-amd64 from boot.

In an attempt to fix GRUB I executed the commands in the 'Reinstalling grub-efi on your hard drive' section of: [URL] ....

Code: Select allmount /dev/sda1 /boot/efi
... surprisingly returned:
Code: Select all$LogFile version 2.0 is not supported.  (This driver supports version 1.1 only.)
$LogFile version 2.0 is not supported.  (This driver supports version 1.1 only.)
Did not find any restart pages in $LogFile and it was not empty.
The file system wasn't safely closed on Windows. Fixing.
Code: Select all[ -d /sys/firmware/efi ] && echo "EFI boot on HDD" || echo "Legacy boot on HDD"

... returned "EFI boot on HDD".

[Code] ....

... Where is Debian?

FULL HISTORY ....
=============================

The laptop came with Windows 8 preinstalled. I switched off Secure Boot and installed Ubuntu for UEFI dual boot. I recall having to use Boot Repair to get the GRUB boot manager working properly for both systems.

Recently I decided to replace Ubuntu with Debian 7.7 and first cloned the entire hard drive to a USB drive (The Clone Drive). This drive successfully boots into Ubuntu in UEFI mode.

Following this I took the opportunity to update Windows to 8.1, which broke GRUB as expected, so that the machine would only boot straight into Windows.

I installed Debian from a live USB stick in the mistaken belief that it would be bootable in UEFI mode. It did boot OK in legacy mode.

I then burned the full Debian 'DVD' image to a USB stick, booted it in UEFI mode and reinstalled Debian. In UEFI mode GRUB allowed me to boot into both Debian and Windows.

At this point I tested The Clone Drive. It was still able to boot into Ubuntu as previously, but after powering down, unplugging The Clone Drive and rebooting, the GRUB menu failed to appear and the machine booted straight into Windows. This is its current state.

Debian Installation :: Dual Boot UEFI - Grub Not Recognizing Drive

Mar 24, 2015

I've set up a dual boot system with Debian and Windows 8, both installed on their own drive, with their own boot partition. I installed eveything in UEFI-Mode with fast- and secure boot turned off. Both installations are working, as I can access them by changing the boot priority in the Bios. What I cannot achieve is to let grub boot my windows installation.

This is the output of parted -l:

Code: Select allModel: ATA Samsung SSD 840 (scsi)
Disk /dev/sda: 128GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number  Start   End    Size    File system     Name  Flags
 1      1049kB  512MB  511MB   fat32                 boot
 2      512MB   111GB  111GB   ext4
 3      111GB   128GB  17,0GB  linux-swap(v1)

[Code] .... 

As you can see, my linux install is on sda, my windows install on sdc (sdb beeing a data disk). This is the entry I made in the 40_custom file in etc/grub.d:

Code: Select allmenuentry "Windows 8.1" {
insmod part_gpt
insmod chain
set root='(hd2,gpt2)'
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
boot
}

I think this should be fine, but if I choose the windows entry wehen grub is booting, it says: error: no such partition. It's my first debian installation, and I am stuck here. Not too much of Linux experience in general.

Debian Installation :: Dual Boot GPT UEFI - 8.2 And Windows 10

Dec 15, 2015

I'll start off with stating my problem and summarize how I got to it.

I installed Windows 10 on an SSD. I installed Debian 8.2 after it. The SSD was/is a GPT disk. I installed both installations from a UEFI booted device (DVD for Windows, and USB drive with Live CD for Debian).

I tested it after each installation making sure I could boot via UEFI into Windows, then Debian, then Windows, to make sure nothing broke.

I rebooted the machine. Suddenly, no more UEFI. Nothing. I didn't change any BIOS/UEFI setup menu settings. Not even my USB drive with Live CD will boot through UEFI anymore. Even when nothing else is plugged into the system.

My situation is actually a bit more complicated than that, but I think that will suffice for now. I can still boot into the Live CD on the USB drive, just in Legacy mode only. I mounted the EFI partition on /mnt/boot after I mounted the file system for Debian on /mnt. It is identical, as far as I can tell, to as it was before when it was working.

My motherboard has CSM and Secure Boot, both have been set up how they need to be to boot UEFI into Debian. Tinkering with them further after things broke did not fix it. I tried all variations of options/settings.

The GRUB Reinstall guide says to be in EFI mode before starting it, so I can't do that.

My motherboard is an ASUS X99 Deluxe, and I've heard ASUS has special "features" (read: bugs) that come with their boards. Searching hasn't brought up any other people with this issue. I believe the firmware is updated to it's most current one.

I've tried dd-ing my backup of my old system, from before trying to migrate to a Dual Boot system, to the SSD (after backing up the dual boot setup with dd -> <name>.img via the Live CD USB). However, that won't boot either as it is a UEFI install as well.

The layout of my EFI partition is as such:
/boot/EFI/Boot/bootx64.efi
/boot/EFI/Microsoft/<Microsoft-naming>.efi
/boot/EFI/debian/grubx64.efi

I've heard that the standards on how that's supposed to be set up isn't a standard. However, since it worked booting into the OS' the first time, I don't see how that could be the issue (a bad hierarchy layout leading to the UEFI not being able to see the OS installs).

I've seen that I can boot to an EFI shell (called Shell.efi, apparently) via an option in my UEFI BIOS setup menu on my motherboard. Is that an option here to somehow bypass this strange issue?

All I can think to try is burn it all and start over. But not knowing what caused it means I could just make it happen again. Plus, I can't boot into UEFI install media, so I can't install UEFI boot OS'. :/

Debian Installation :: No Operating System Found After Install UEFI?

Jan 30, 2015

I'm trying to install debian and when the installer starts it UEFI at the top, instlal completes however on reboot it says 'no operating system found' i've read it can be because of UEFI but I have tried different bios options but to no avail.

Bios options

Debian Installation :: Jessie UEFI System Boot Menu Missing?

Feb 17, 2016

I have installed Debian Jessie 8.0.3 64-bit net install on an IBM ThinkCentre. I have earlier had a dual boot Win 8 and Ubuntu 14.04 installed on the computer. When I installed Debian Jessie, I deleted the Ubuntu partitions and created new partitions from the free space. The install went fine and the Debian EFI/UEFI version of Grub was installed, but clearly at some other place, as when I boot the system, the old Ubuntu Grub pops up and of course cannot find the necessary files that it is looking for.

Debian Configuration :: Completely Removing Microsoft Bootloader From UEFI System

Jul 16, 2015

I have a Debian testing system on a laptop that used to have Windows 8 on it. I kept the EFI boatloader and its partition, but now every time the system boots, it first tries to boot into Windows (which isn't there anymore). Removing /boot/efi/EFI/Microsoft just leads to an error message when booting, with some component of Windows still trying to load and not finding those files.

The workaround for now is to go into the UEFI boot menu on every boot and selecting the "debian" entry, which works but is a bit cumbersome.How can I get rid of the Microsoft loader completely? I find a lot about repairing or re-adding the Windows bootloader, but nothing about removing it.

Ubuntu Installation :: Can't Boot System 1 TB In UEFI Mode?

Aug 16, 2011

I tried to install Ubuntu 11.04 on my 3 TB hard drive but UEFI firmware can't boot that Linux partition anywhere and went Windows 7 instead. Does anyone have any solutions for UEFI booting? I think EFI filesystem is messed up or bug in installer. Earlier I was able install and boot linux partition with both linux distros (Ubuntu and Fedora) before I removed them for re-install them later and created additional NTFS partition until now.

However, I was only able boot Ubuntu 11.04 from USB stick in UEFI mode. I will continue to use live USB until all solutions are solved. UPDATE: I made a data backup on one of NTFS partitions and removed it. I tried to install Ubuntu 11.04 below 1 TB disk space but still can't boot it.

My system configuration is:
ASUS Maximus IV motherboard
Intel i7-2600K processor
8 GB memory modules
Hitachi 3 TB hard drive
MSI HD 6870 Hawk video card

Debian Installation :: Booting Jessie 64b With UEFI From USB

Sep 30, 2014

I have this new computer (MSI Ge70 2PE Apache Pro) that came with Windows 8 and UEFI. I freed space to make a partition to install Debian testing 64bits on the same HD where Windows is. I had no problem making the partition but after that I tried making a bootable usb to install Debian using the dd command and it didn't work. So I tried with an install dvd and even when I changed the boot order in the bios it didn't work.

After reading some more I realized that there could be a problem trying to boot a normal installation dvd with UEFi so I disabled Secure Boot and then switched the boot mode on my Bios to UEFI with CSM. Again it didn't work and it booted directly into Windows. So I switched the boot mode to Legacy. This time Windows didn't boot directly but I get a "Reboot and Select proper Boot device" message on a black screen.

I now realize that I need to install a UEFI "version" of Debian along the UEFI version of Windows 8. I guess that's why it didn't work with the Legacy boot mode. URL...The installer does not provide a convenient way to install an UEFI boot loader, so you are going to install a regular BIOS boot loader at first, and switch to UEFI later.

Use the expert mode and format your hard drive with a GUID Partition Table (GPT). Create a small partition (1 MiB would be far enough), type it as a BIOS Boot Partition (this is the untitled flag above the “bootable” one in Partman), do not format it and do not mount it: this will be needed for BIOS booting. Create another small partition (same kind of size), type it as an EFI System Partition (this is the“bootable” flag), format it as FAT and mount it on /boot/efi: this will be needed for UEFI booting.

Debian Installation :: Disabled UEFI Secure Boot

Sep 26, 2014

I have Acer Aspire S7-392. It has two 128GB SSD drives. They are using RAID 0. Currently there is Windows 8.1 installed on the RAID 0 drive.I am trying to install Debian 7.6 (wheezy) alongside Win 8.1 (dual boot). Actually I have already created linux partitions and installed mentioned Debian on my computer. I had to skip grub installation due to fatal error that had occurred. (Everything on existing RAID 0 volume).Now I am looking the way to install grub and boot Debian. I have disabled UEFI Secure Boot. It didn't work.

My question is:

1. Is it possible to have Win 8.1 and Debian dual-bootable on the same RAID 0 volume? How to install grub and boot debian?

2. If not, what am I supposed to do to achieve what I want (these two systems on one computer)? Delete old one RAID 0 and create two new: one for windows and one for linux partitions?

Debian Installation :: Wheezy 7.8 UEFI Boot Commands

Feb 6, 2015

I have a server in which I'm trying to install Debian into. There's no BIOS, only EFI boot. The vendor locked it down so there's no way to see it or get into it.

The Wheezy 7.8 netinst CD has EFI boot parameters and works on everything I throw it in, except this one server. Booting it up, the code doesn't see the EFI and boots into normal mode, negating every chance to install it (dozens upon dozens of failed installs).

During boot, I press the [TAB] at the Debian Linux installer menu and get the load parameters (/install.amd/vmlinuz vga=788 etc). What parameter can I add to this line to get it to run in UEFI mode so we can install it?

Debian Installation :: UEFI Dual Boot With Two Distributions?

May 27, 2015

I have Debian installed but I need to dual boot with distribution based on Ubuntu 14.04. This is my first UEFI dual boot install attempt. And I must do it right. I must not lose my Debian !

Code: Select allDisk /dev/sdb: 232,9 GiB, 250059350016 bytes, 488397168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt

[Code] ....

Ubuntu will go to /dev/sdb5 but I don`t no for sure what to do when installing Ubuntu. How to select during install existing UEFI partition(/dev/sdb1) so Debian and Ubuntu can use it. Can I select existing UEFI partition like I would do for /home or /swap ? Will this work ?

And what will happen with Grub if I select install grub ? I want to manage grub from Debian, it is my main OS. Can I skip Grub install and just update grub on my debian after ubuntu install ? Or I just install grub, then after completed Ubuntu install I install it again from Debian. Will this work ?

Is procedure of installing dual boot trivial like before or UEFI hide`s some unpleasant surprise.

Debian Installation :: UEFI Won't Find Boot Device After Successful Install

Sep 12, 2014

I installed Debian Jessie (netinst, daily snapshot) on my Acer Aspire V5-123 laptop in the UEFI mode with the secure boot turned off. everything (network, hardware, partitioning, ...) went smoothly to the last step, but after removing the boot media (USB stick) and rebooting, the firmware could not find the boot device ! The only thing I can think of, is that the EFI boot is not set up properly by Debian installer, but I don't know how to fix it.

Debian Installation :: No Automatic Boot UEFI Dell Latitude E6410

Nov 20, 2015

I just installed Debian jessie on my Dell Latitude E6410 using the UEFI install. No everything went well during the install, but after the install the first boot i ran into an issue that the laptop will not boot.

When I go in to the boot menu of the Dell Latitude E6410, I see that debian has created a uefi name (Debian)

When I select this, it boots without any issues. After again a reboot again, no luck still a black screen during the boot.

Seems that the only option to get my laptop booting is by pressing F12 and select Debian in the UEFI boot of the laptop.

Is there any way i can get my laptop to boot Debian directly from UEFI, without having to press F12?? (Also disabled all legacy devices to start up but no luck)...

- Debian Jessie X64 (Using 32/64 network install, via USB)
- Dell Latitude E6410 i5 (1280x800 intel graphics) latest bios A16
- SSD drive (Samsung 470 series)
- Debian is the only OS installed

Debian Installation :: Asus H97-Plus - UEFI (Secure Boot) / Black Screen Install

Aug 29, 2014

I appear to have the exact problem that is currently listed in the 7.6 errata about EFI boot and black screen while trying to install ("Potential issues with UEFI booting on amd64"). The problem is that their workaround is not an option for me. This is a new rig and the motherboard doesn't appear to have any kind of ability to disable secure boot. I also don't know if my problem is exactly what they're thinking when it comes to that entry.

I'm able to get to the Grub install screen where you have the option to install Debian but when I select an option (any option) the screen turns off, back on but is black. All activity in the system stops after a few seconds (3-5 seconds) and that's it, she's done. I've tried all the options to try and disable secure boot but the options listed below are as close as I can get (and apparently should be sufficient).

The CD ISO used was the 7.6 netinst CD. I've also tried the Jessie ISO (Testing) that was downloaded about 2 hours ago. Same results. Unlike the errata which says "intermittent booting problems", my issue is consistently reproduced with no other result no matter what I do.

The rig:
-Asus H97-Plus running revision 2202
-Intel i5-4570
-32GB DDR3-1600
-128GB SSD Drive
-No external video card - using on board only but have tried both VGA and HDMI ports with the same result.

BIOS settings (is it still called BIOS or is it UEFI now?)
-Fast Boot: Disabled
-Launch CSM: Enabled
-Boot Device Control: "Legacy OPROM Only" or "UEFI and Legacy OPROM" (tried both)
-Secure Boot State: Enabled (it's grayed out and I'm unable to change this)
-OS Type: Other OS (supposedly makes it so you can boot non-Windows OS)

The Debian page with the errata: [URL] ...

Look for "Potential issues with UEFI booting on amd64"

The obvious suggestions I've tried:
-tried USB boot & CD boot - same result
-tried altering the grub script to add the ACPI options - no effect

Debian Installation :: Jessie Stuck At Loading Initial Ramdisk - UEFI Mode

Oct 2, 2014

So I managed to install Debian Jessie on a MSI G70 2PE Apache Pro that came with Windows 8.

First I partitioned some space on the laptop. Then I put on the net install cd for Debian and installed it on UEFI mode. It installed correctly.

Now I'm on Grub and when Debian tries to boot it gets stuck on "Loading initial ramdisk". The cursor under it doesn't even blink. The only way to get out of there is by Ctrl-Alt-Delete. Secure Boot is turned off. Fast boot is also off. If I try to boot on recovery mode gets stuck all the same.

The options on my grub are

Debian GNU/Linux
Advanced options for Debian GNU/Linux
Windows Boot Manager (UEFI on /dev/sda2)
System Setup.

If I choose the Windows option, Windows boots, no problem.

If I choose the edit option for the Debian entry this is what it shows

Code: Select allload_video
insmod gzio
insmod part_gpt
insmod ext2
set root='hd0,gpt6'
if [ x$feature_platform_search_hint = xy ]; then

[Code] ....

What is happening and what should I try to make this work? Could it be a graphics card issue since this computer has a Nvidia Gpu?

Debian Installation :: Grub Can't See Windows 7

After that I installed debian on a third different logical partition of my disk and then only debian was running and windows and ubuntu didn't. Ubuntu does not seem even when the computer starts! Then i reinstalled ubuntu over the debian so i can run only ubuntu. I cannot see windows 7 at all when grub starts

Debian Installation :: Remove GRUB Boot Loader From My System?

Apr 3, 2010

I've had to give up trying to install linux. It just won't work on my machine, a Presario 6370us that has been upgraded over the years such that it is not compatible with linux, apparently. (You can read my travails elsewhere on this board; thanks very much to all who tried to help.)

Now, how do I remove the GRUB boot loader from my system? I need the system to boot directly to Windows XP.

I can't start linux in any way, shape, or form, so I need to either edit GRUB inside the GRUB environment itself, or to do so from Windows.

Ideally, I'd like to remove GRUB entirely. Failing that, I'd like to edit the GRUB config file so that only Windows is an option. Failing that, I need to make Windows the default OS.

Debian Installation :: 8.3 And Windows 10 Dual Boot GRUB EFI Removed

Feb 3, 2016

I've been using Debian for a few years but always on dedicated boxes and/or VMs.

Finally decided to dual boot Debian and Windows on my main Desktop PC.

Installed as I normally would using, however this time using a seperate drive (one for the existing Windows 10 install and the other for Debian), Debian install detects that windows has an EFI partition and sticks an entry in there, which is fair enough, and everything working fine. Then I spent some time configuring all my software and set it all up just the way I like it. I've rebooted Debian a few times to check it's working correctly and it is.

The issue arrives when I reboot and load into Windows 10. It boots fine.

However after a further reboot GRUB no longer loads... and the machine just boots directly into Windows 10.

After doing some further digging into my EFI partition (and reinstalling various times) it would appear that after a reboot Windows 10 deletes the entry GRUB creates in my EFI partition after EVERY reboot.

Done some googling and most people advise turning off 'fast boot' in Windows as it locks certain partitions to facilitate the machine going into hibernation, only to find that it's always been turned off on my machine (I recall due to a driver issue with my graphics card this had to be turned off when I installed Windows 10).

I've found this article on the Ubuntu forums : [URL] .... however I've tried their steps and windows is still doing a hostile takeover of my EFI partion after a reboot!

Any way to stop Windows 10 from interfering with my EFI files after a reboot? (without doing the obvious thing and kill Windows off).

Debian :: Recovering Grub After Windows Installation - Encrypted Partitions And LVM

I managed to install GRUB after following this guide and using an Ubuntu 10.04 graphical installation disc, but I only get to a GRUB CLI when booting, so I can't actually choose an OS there.

I tried following this guide but I'm stuck after "# Mount the partitions to /mnt/root" and don't know what to do.

Does anyone know how I can fix GRUB so I get to choose between Debian and Windows 7 there?

Debian Configuration :: Cannot Boot 8.0 Live USB From UEFI

Jun 18, 2015

On a new Lenovo Thinkpad T450s, I encounter the following issue: The USB drive containing live CD image ("burned" to the USB using mkusb tool --> which in turn uses dd) cannot be booted from the UEFI boot loader. I have to reconfigure the hardware (BIOS) setup to support both UEFI & legacy system, and with first boot priority given to legacy (BIOS-style) booting. But if I do this, I don't see the UEFI system in the /sys/firmware/uefi directory. I am using the 64-bit live CD image (debian-live-8.0.0-amd64-xfce-desktop.iso).

This is my goal: to boot the live USB from UEFI, so that I can install it in a form that is UEFI-bootable.

Fedora Installation :: UEFI 14 Without DVD?

Thought maybe there was some error in the iso, I downloaded again and the result was still the same. How do I fix this? I prefer not to burn DVD coz I dont have one and in my city, if you want to buy DVD you have to buy one bundle which is expensive for me.

I read the manual/documentation, it say I only can use minimal booting, I see the command line, which bassically copying the efidisk image and it ended there. No further information. What should I do next? Do I have to follow the command? But I am using Windows 7 OS, not linux. Earlier I'm using Daemon Tool as a Virtual DVD Driver and copied the efidisk.img to my USB. I restart my OS but it then go staright to Windows eventhough I set my laptop first booting for my USB.
