A friend is having trouble booting Natty from the live CD in order to install ubuntu. Grub is giving an error message "Error: prefix not set". or something like that when he tries to boot from the CD. My friend is speculating that it can't boot because it's an uefi drive. he got a lenovo thinkpad.
View 1 RepliesI have a UEFI MOBO and I cannot get 11.04.2 beta2 AMD64 to install. Everytime it hangs at the GRUB2 install and the install breaks with /target created. Anyway, is it possible to install 10.04 AMD64 LTS as bios, boot into it and then edit the front partitions to make the needed UEFI partitions, install GRUB2 and manually build the UEFI boot files necessary for UEFI booting? If so, can some one help me out with the most likely path to follow?Am comfortable editing partitions in GParted and Disk Utility, using command line, and can follow directions well. Am not concerned about data on the disk so this can be done as many times as necessary.

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.

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.
I'm trying to test out UEFI boot and install with Fedora 13. It looks like it is not supported...at least not in the standard x86-64 DVD image. Running 'dumpet' on the .iso shows no EFI boot section (whereas, for example, RHEL6 Beta-2 x86-64 DVD .iso does show one); see output below. Will there [ever] be UEFI supported boot/install CD/DVD .isos for Fedora?

Ok so I have a UEFI compatible notebook. I managed to take the natty-desktop-amd64 (the latest Alpha, 3 in this case), throw it on a SD card, and started the grub2 bootloader via UEFI.
Ubuntu installed just fine, the only problem is, there is no selection in my UEFI bootloader for Ubuntu. I can access my newly installed Ubuntu partition only via the "Try Ubuntu Before Installing" option on my SD card. So is there anyway I could create a boot entry?
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?

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'. :/
As you probably know Debian LIVE ISOs is not (U)EFI bootable since there is no EFI bootloader on them. I need to boot usb for uefi mode...

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-live-8.2.0-amd64-xfce-desktop.iso do not boot in uefi mode. I would like to know if live image can boot uefi mode? If not how can I do later from bios to install grub efi?

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.
View 11 Replies View RelatedI'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.

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

}
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 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)...

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.
View 9 Replies View RelatedI 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've got two laptops running Ubuntu. Both have had Lucid installed from the live cd. I have upgraded one of them to Maverick. Both distributions are running great after they boot up, but I haven't experienced any faster boot times with either distibution. Both boot to Bios and then the screen goes black with a blinking cursor in upper left corner of the screen. The black screen remains for 30 to 45 seconds and then I get the Ubuntu splash screen for maybe 5 seconds, and then desktop. Why am I not seeing faster boot times? I realize 45 to 60 seconds is good compared to other os's, but I anticipated much faster boot times. Shut down on the other hand is quite fast at maybe 5 to 10 seconds. Does anyone else get this black screen on boot? Seems like wasted time cause I can't tell what's going on during the time there is a black screen. This is not a real big deal breaker, as I don't reboot very often, but I just wonder why bootup isn't faster.
View 7 Replies View RelatedWell today I decided that I couldn't wait for the offical release of 10.04 LTS, so I upgraded from 9.10 to 10.04 LTS Beta 2. After realizing that many problems had come with that update, I decided to just format my Ubuntu partition and reinstall it. Somehow my GRUB stopped working from when I formatted Ubuntu, so I whipped out the old Toshiba recovery disk for Windows Vista 32bit. After many attempts to have the recovery portion of the disk fix all of my problems and seeing no results, I decided that reinstalling Ubuntu (and GRUB) might make everything all better. Well it didn't. Grub shows my Windows partition but fails to boot it. After selecting it, it goes to a blank screen and stops responding. And to add to all of my problems, my BIOS has changed slightly. It no longer shows/or responds to F2 or F12 when I tried to give another try at that Toshiba recovery disk. That kinda sucks since I can't choose what to boot. Please help me!! I really don't want to have to format my entire hard drive and try to install Windows Vista again (Not that Vista is anything anyone should love) I have many expensive programs that can only be activated a certain amount of times. I don't even think that I could reinstall Vista since my BIOS won't let me boot the CD/DVD drive.

View 1 Replies View RelatedI understand this is not directly an ubuntu issue, but this arose as I was trying to install ubuntu, so I'm hoping some kind souls on here would be good enough to help anyway.
I've in the past installed ubuntu on to my PC using a CD, but this time I thought I'd try creating a USB startup disk.
I was required to set up the BIOS to change the boot order so I can boot from the USB flash drive.
The problems arose when I pushed the 'DEL' key (the correct key for my motherboard) to access the BIOS setup. When doing this the computer completely froze and would not progress any further to boot. It would still boot normally from the HDD provided I didn't try to enter the BIOS.
Looking on the internet for a solution I tried using the motherboard jumper to reset the CMOS. Now I can't boot up the computer at all. I get a message saying 'CMOS checksum error - Defaults loaded' then it asks me to press F1 to continue. I try this, but nothing happens. Clearing the CMOS has made things worse as now I can't get the computer to boot at all.
Have I killed my motherboard somehow? I've tried using a different keyboard (one USB and the other a USB keyboard but with an adaptor to connect it to the P/S2 port).
On further investigation any key press from the keyboard is enough to freeze the computer at whatever point.
My motherboard is an WinFast NF4SK8AA with AMD Athlon processor and 4Gb of mem.
