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.

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.

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 !

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.

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'. :/

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.

I've run Debian on my laptop for quite some time now with no problems. I installed Slack to a new partition created in the free space of my hard drive, and I thik this was my mistake: I let Slack automatically configure the MBR with lilo (can't remember - I should stop operating on the MBR at 4 AM.) Now Slack runs just fine, but upon bootup I would like to be able to boot either Debian or Slack, but instead I just have a Slack splash and the only option is to press enter to boot Slack.
Code:
I believe sda1 is the root directory of my Debian install.
Code:
In the above table, sda10 is the swap I created for Slack and sda3 is the root directory for Slack. All other partitions were there before (my initial Debian install).
Thus my partitions are apparently intact and visible by the MBR (is it correct that the MBR holds the list of partitions on a disk?) but for some reason I don't have the option to boot Debian at all - just Slack.
I have a feeling this is a LILO/GRUB issue, but I don't know where to start.
EDIT: more poking around seems to reveal that it is the configuration of LILO that is the problem. Observe the following output:

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?

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?

I'm inexperienced in Debian. I have a dual-boot machine (64-bit, Debian 7.3, Windows 7, legacy boot) and encouter a problem at boot ever since I completed the installation of Debian 7.3 alongside the exising Windows 7. This machine has six hard drives: two are intended for ntfs storage of general data (raided together by RAID1); two more are intended for ext4 storage of general data (also raided together by RAID1); the fifth contains the Windows OS files and the sixth contains the Debian OS files. The problem is that I arrive to the grub_rescue each time at boot, seeing the message:
GRUB loading.
Welcome to GRUB!
error: no such device: e081517b-3399-4067-9294-8f0686f753ca.

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).

I installed Win7 after Ubuntu (10.10). I attempted to reload grub so that I would be able to run them dual boot and now I can't load anything.
I followed the guide here: [url] and went threw it a couple of times now to make sure it wasn't user error.
I am using a live cd from 10.04 because it's the only one I have. Any chance that's why it isn't working properly? I wouldn't think so, but I assume that it's possible.
If that is the case; Any way to solve it without using the live cd? I cannot burn a new disk because I have to boot from disk to use my computer right now.
I just get a flashing cursor on a blank screen when I try to load.

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.

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

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.

My laptop setup is:
sda1: W7
sda2: FAT16
sda3: /boot
sda4: encrypted LVM with debian (everything besides /boot)
now I've re-installed W7 so grub was overwritten. I've tried the procedure which worked for me previously:booting with the netinst usb in rescue mode, choosing a root partition to mount, using grub-install to reinstall the grub:
Code: Select allmount /dev/sda3 /boot
grub-install /dev/sda
Now I'm on Jessie (stable), and this time this fails, and I am able to mount only sda3.grub-install doesn't exit so I'm assuming it has been replaced by `grub-installer'. also '/boot' doesnt exist so I created it manually.
Code: Select allmount /dev/sda3 /boot
grub-installer /dev/sda
The latter fails with
Code: Select all/dev/sda/proc not a directory

I cannot count how many times I have re-installed squeeze, and do all kinds of fixes to grub, but no joy. Every time, there is this ntoskrnl.exe error, and to re-install it. I thought my WIN XP may be corrupted, so I reinstalled it, and updated it with sp3 and all updates. Then I re-installed squeeze (reformatting all partitions). At the end, the installer ask if I want to install grub to mbr. I replied yes. After reboot, only the 2.6.32.3-amd64 and the recovery kernels show up on the grub screen, no winxp.OK, I booted into squeeze kernel and looked at the /boot/grub/grub.cfg file, and there winxp is not included in /etc/grub.d/30_os-prober section. In terminal, I typed
#os-propber and it found winxp in /dev/sda1
then I typed
#update-grub
and now /etc/grub.d/30_os-prober now show winxp.I rebooted, and winxp shows on the grub screen, and I chose winxp.It came back with "ntoskrnl.exe ...error... re-install ntoskrnl..."Here are the details:

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

I installed Debian on my PC and then installed Ubuntu. This worked fine and I could dual boot between the two. The PATA disk was /dev/hda on debian and (I think) /dev/sda on Ubuntu. I copied the entire disk to a sata disk using dd from knoppix and put the PATA one to one side. Now the Ubuntu comes up fine but when I boot debian, it complains about references to /dev/hda1, which is present in grub - root=/dev/hda1. Debian now expects sda references rather than hda references. How do I persuade Ubuntu to write /dev/sda1 to the bootloader rather than /dev/hda1 using grub-mkconfig?

Ubuntu 9.10 was set up to handle the booting selection - previously I thought it was xp but Ubuntu 9.10 "did" it. The system started out as a xp / ubuntu 9.10 dual boot on a 400gb drive. xp has 210gb, ub has 80 and their is a 100gb shared storage. Xp was installed first and then I followed a guide over at linuxconfig.org to get ub installed so that I could select which OS was wanted at boot. Ubuntu manages the boot up menu (Went back to look at my notes from the original setup) The owner tried to update to ub 11.04 and afterall was said and done the machine now boots to the message
error file not found grub rescue I can't say if 11.04 was properly installed or not. Ask whatever you like and I'll give the best answer I can. I think the xp install is okay but I can't say for certain as I don't know how to boot it outside the bootmanager at startup. Data has been saved so if I have to blow it all away and start over I can but I'm hoping I won't have to.

So my computer has ubuntu 9.10 installed 1st and I want to install win 7 in a separate partition. Basically, ubuntu 1st, win 7 later so far from what I learned from search results, grub 2 have problem with win 7 installed later and what was recommended was install win 7 before ubuntu. how ever I do not have the time to start over again because there are too many things to back up or install again. can I simply revert grub 2 to grub 1 again and resolve the problem?

PC specs: i7 920, Ati HD5870, 4GB ram Installing Ubuntu 10.04 from a USB stick. The stick is fine as I installed Ubuntu on my laptop with it no problem.
Problem #1: The grub boot manager is missing. The first time I installed Ubuntu it appeared as usual and let me choose between windows 7 and ubuntu. Due to the black screen issues I uninstalled Ubuntu. Since then, every time I've tried reinstalling it I don't get the grub boot manager, instead my PC goes straight to windows. I have formatted the partition I installed Ubuntu on, as well as installing it on another drive, to no effect.
Problem #2: After the Ubuntu splash screen, I'm greeted by a black screen. After a few seconds my monitor goes into standby. Ctrl+alt+f1 does nothing, and removing quiet and splash from the command line didn't help either. I hear I need to use vesa drivers but I have no idea how to go about this when I can't even get the OS to start in the first place.

This is the third time I try unsuccessfully to install Debian as a second OS on a hard drive. When it gets to the end of the installation process the installer asks whether I want to go ahead with the Grub Boot Loader, I choose yes. The end result is however that I can't boot that partition within the hard drive -- i.e., Debian. Can someone tell me what is going on? Should I not use the Grub Boot Loader when I have more than one operating system on a machine? Should I not install Grub on the Master Boot Record (MBR)?

I had a dual boot machine with fedora 12 and windows vista and I could use grub boot-loader to switch between two. Few days ago windows got corrupt and I have to reinstall it. I put windows 7 now and as usual it erased grub. So to reinstall I put the fedora 12 installation CD on and followed some usual setup steps. When I got the command line I issued the command "grub-install /dev/sda" (sda not hda because It showed bunch of sda, sda1..) but surprisingly it said grub command not found. I remember doing it before while it worked fine.
