Installing BURG left me with Grub Prompt topic






Fresh install of 14.10 on dual boot with win xp on an old net book. I managed to set up Grub to boot option into Win XP listed first. I pushed my luck attempting to "decorate" and installed Burg (which I learned since hasn't been supported since 2010). Now I'm left with a bunch of text and a Grub prompt "grub >" prompt after reboot. I'm a total noob with Linux and would appreciate any help in recovering from this hell I found myself in- a least painful method would be awesome.






[other] Grub shows only minimal bash on UEFI/Win8 System topic






I am trying to install Zorin 9 along Windows 8. If i deactivate UEFI, Windows cannot boot so i need to have UEFI on all the time.

Computer: Acer Aspire Laptop

I told the Zorin installer to put the bootloader directly on sda, not a ceratin partition, because i didnt want it to shoot down the windows loader. After the install, i only get the grub minimal bash and have no idea what to do. ( i still can boot windows by using a special function "choose boot device" of the BIOS, so the windows loader appears to be fine, but normaly after switched on, the broken grub appears)

Tried bootrepair on live CD, it didnt help: http://paste2.org/_dbIdFkMd

Also, the folder /boot/UEFI is empty, on the Zorin partition.

[ubuntu] Clean install ubuntu, only GRUB commandline shows up topic






Hi,
Is there anybody out there?
Just nob if you can here me..

Im just kidding, I bought a new notebook acer aspire e11 yesterday with preinstalled windows 8.1, I go straight to install ubuntu 14.04 , I create partition as instructed in this link
http://www.tecmint.com/ubuntu-14-04-installation-guide/
However, when clicking install, theres warning message that I have to create boot partition ( not /boot) and define it as EFI mode. I gave it 200mb. However, after install, there is no bootable device, only grub commandline appear. I logged into bios and setup my only hard disk as first priority, but its still remains.

I tried boot-repair with recommended options, but situation still the same.
Heres the diagnostic result

Anyone help me please






Ubuntu 14.04 Grub Error After Install Win 8.1 topic






Last year I blew away my Windows 8 trying to work through some Ubuntu 14.04 upgrade issues. I recently saw a Youtube video where Windows 7 was installed on an Ubuntu 14.04 PC.
Step 1. I shrunk my Ubuntu partition
Step 2. Successfully installed Windows 8.1 on the unallocated space (240GB)
Step 3. Used Easy BCD 2.2 to create Ubuntu boot menu. I saw Ubuntu on the hard drive. After installation, the computer boots to the Grub Rescue> prompt. Cannot get back to Windows without resetting PC.
Step 3. Reset PC, then rebooted using live Boot-Repair boot USB. Boot repair will not repair Grub with message 'Filesystem repair requires to unmount partitions. Please close all your programs. Then close this window.' My boot information report is at http://paste.ubuntu.com/10177356/.
Is my Ubuntu salvageable? If so, I need simple step by step actions to accomplish. Any assistance will be appreciated.

GRUB configuration topic






One of the greatest advantages of GRUB is customizability.
Especially the possibility to boot from ISO files is a big 'plus'.

You don't need to burn a CD or create an USB disk anymore.
The only exeption is when you can not boot to GRUB menu.
Then naturally you need to have such a separate boot media.

You just have to create a menu entry and you are ready to go.
This is my setup meant to serve as an example for illustration:

gksudo gedit /etc/grub.d/40_custom

menuentry "clonezilla" {
set isofile="/ubuntu/clonezilla-*.iso"
loopback loop (hd0,5)$isofile
linux (loop)/live/vmlinuz boot=live config union=aufs noswap noprompt vga=788 ip=frommedia toram=filesystem.squashfs findiso=$isofile
initrd (loop)/live/initrd.img
}


menuentry "gparted" {
set isofile="/ubuntu/gparted-*.iso"
loopback loopg(hd0,5)$isofile
linux (loop)/live/vmlinuz boot=live config union=aufs noswap noprompt vga=788 ip=frommedia toram=filesystem.squashfs findiso=$isofile
initrd (loop)/live/initrd.img
}


menuentry "ubuntu-rescue" {
set isofile="/ubuntu/ubuntu-*.iso"
loopback loop (hd0,5)$isofile
linux (loop)/casper/vmlinuz.efi boot=casper iso-scan/filename=$isofile noprompt noeject
initrd (loop)/casper/initrd.lz
}

sudo update-grub

(* = file name | hd0,5 = disk 1 / partition 5)

[ubuntu] Grub question-s? topic






My machine is an HP DM1 with 14.04 Gnome installed and I've been using Ubuntu Linux a long time. The grub file has always been somewhat of a mystery which has lately gotten even more so. At least two problems here:

One, I tried out different desktops lately (using apt-get install xubuntu desktop for instance) and now can't get rid of the resulting trash they generated (eg: the flash screens) I have uninstalled most of them manually with terminal commands but one, Kubuntu, remains.

Secondly: I counted 60 previous versions of the kernel in my grub this morning and am wondering if those are really full kernels cluttering up my hard drive. If so how do I get rid of most of them - I would assume that 4 or 5 would be sufficient for backup in case of a glitch in a new one. BTW, I update daily.

Another problem which appears to be getting more frequent: I lose my keyboard input more and more often lately. I realize it could be a hardware problem; is there any way to determine that?

Sorry if there are too many topics here. Trying to be economical.

GRUB repair topic






Having read about problems to restore GRUB I tried different methods.
Now I want to share the easiest and most secure way that realy works:

Boot from ubuntu install media.
Execute commands in terminal:

Solution for GPT partition table | EFI mode
(X=disk | Y=root partition | Z=EFI partition)

sudo mount /dev/sdXY /mnt
sudo mount /dev/sdXZ /mnt/boot/efi
for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done
sudo chroot /mnt
grub-install /dev/sdX
update-grub

Solution for MSDOS partition table | MBR mode
(X=disk | Y=root partition)

sudo mount /dev/sdXY /mnt
sudo grub-install --boot-directory=/mnt/boot /dev/sdX






Error 22 GRUB topic






I'm having an issue with a Lenovo B570 having a weird error. Whenever I turn it on the options to enter the boot menu or the bios are not on the bottom on the screen like always. Then, after the computer boots it just shows "Error 22". I tried installing Android x86.

[ubuntu] Can't access BIOS options on MSI Wind U100 stuck in Grub Rescue topic






My main problem: I can't access BIOS boot options on my MSI Wind U100. I get the main BIOS screen, but it's conspicuously missing the "hit del for options" that used to be there--and when I try hitting various F keys and/or del, nothing ever brings up any option. Instead, I just go straight to Grub Rescue, and I can't get out.

Why I want to get to boot options: because I have a Windows XP bootable USB that I want to use to get into recovery mode and fix my MBR. But I can't figure out how to get that USB to boot when BIOS won't cooperate and when my only other option is Grub Rescue.

How I got in this mess:
I was dumb. I had a dual-boot Ubuntu/Windows XP system that I wanted to restore to factory default, with Windows only. So in Windows I deleted the Ubuntu partitions and rebooted without fixing MBR first. Ugh.

To fix the problem, on another computer, I made my XP bootable USB, but as I said, I can't get my Wind to boot into it (or anything else, or give me any BIOS options at all). Any suggestions? (I've read a lot about Grub Rescue, but it seems that it doesn't have USB drivers...?)
