GRUB Xubuntu Boot Problems
I had been using Xubuntu 9.10 successfully for some time. Recently, however, I tried to boot Xubuntu, and instead of reaching the login screen, a "GRUB" interface appeared.
The title was "GNU GRUB VERSION 1.97~beta4" Below that, there were a few instructions describing the use of the Tab key and a blank command line interface beginning with "sh:grub7". Before this started occurring, my computer would turn on and then display a menu to choose the OS. If I selected Xubuntu, a few lines would flash by, and the login screen would appear. My computer is a Dell XPS M1530 laptop. The operating systems installed are Windows Vista Ultimate and Xubuntu 9.10. The Xubuntu was installed using a Wubi installation. As far as I remember, I did not make any changes that may have caused this. The only significant event that did occur was a power outage, but my computer was not plugged in nor on at this time. If everything works normally, how would I boot Wubi Xubuntu from the GRUB interface? Are there any other solutions to this problem? Thank you for any help. |
I can't give too much advice, but when the grub menu comes up, hit e and look at the boot settings, this might just be a case of an update gone wrong, in there make sure that your boot options look as they should something like:
Code:
title Ubuntu 9.04, kernel 2.6.28-11-generic Grub2: http://ubuntuforums.org/showthread.php?t=1435808 |
Thank you for your suggestion.
I tried pressing 'e' at every stage and screen of turning on my computer, but it had no effect. I don't seem to be reaching a GRUB menu, just an interface. Pressing 'set' in the command line of the GRUB interface listed some information, including a "kernel: hd0,3". I tried entering "boot hd0,3" and was told that no kernel existed. Again, this is on a Wubi installation. |
Follow the grub2 link above - then go to the link in post 2 of that reference. It is quite a detailed article - and at the end has some troubleshooting notes.
I have no experience with wubi, so can't help you there. |

i encountered the same problem, when i hit the e it says record fail=1 if [ -n ${have_grubenv} ]; then save_env recordfail; fi set quite=1
insmod ext2 set root =(hd0, 1) search --no floppy --fs-uuid --set 1574800c-0386-45f9-a627-449a559d\0ea linux /boot/vmlinuz-2.6.31-14-generic root=UUID=1574800c-0386-45f9-a\ 627-449a599d70ea ro quite splash initrd /boot,initrd.img-2.6.31-14-generic i've read your reply, and it has different root=UUID number, is it neccessary to change to the one that you replied to the other? then after, what will i do? thank you so much. hope you will help me with my problem. thanks |
I've looked through the article for all references to Wubi.
I tried Code:
set root=(loop0) When I enter ls, I get the drives (hd0), (hd0,1), (hd0,2), (hd0,3), and (hd0,5). I've tried sda, sda1, sda2, sda3, and sda5, but I always get the same response. Are there any other suggestions? This is Xubuntu on a Wubi installation. If I do choose to reinstall Xubuntu, is there anything I could do to prevent this issue from reoccurring? |
My suggestion is to not use wubi. I saw a reference from a Ubuntu dev that wubi would be dropped - issues with grub2 IIRC.
I did try and find it later, but couldn't - maybe they changed their mind. I generally use dual boot, but if I have to use virtualisation on Windoze (which I do a fair bit) I use VirtualBox and install Linux (and OpenSolaris) there. |
hi
most ubuntu distros use grub2 with gfxmode so instead of pressing E for edit....press ESCape to escape graphical mode and enter text mode....then press E to edit 2) they have a nasty habit of using hiddenmenu as well. this is best solved by using a live cd to mount your /boot partition using root powers Then part 1 test.... just edit /boot/grub/grub.cfg to put a # in front of hiddenmenu....report if you don't see one pls reboot and if that works....search each file of /etc/default/grub or /etc/grub.d I do not use Ubuntu so am only guessing |
stop mucking around with, renstall it it safes lot hassle

grub2 problems
Cannot understand why it worked ok without alteration unless it was an update/upgrade problem, especially if done on the gui.
Perhaps, boot into a live ubuntu, drop to init 1, 'umount' the relevant partition,run fsck, then reboot and use the (still inserted) to boot from the first hard drive- providing that is where you linux is. Otherwise, after running fsck, remove that disk and use System rescue disk or supergrub to reinstall the MBR. This is only a suggestion. Fred. |
I made a video to show exactly what is happening:
http://www.youtube.com/watch?v=prdt7EXEIq4 I'm beginning to think that I wont be able to recover my system. I'll reinstall it using a proper partition instead of Wubi. Is there any way at all to get my files back? In Windows Explorer, I can find the folder that Wubi created. I assume that all my files are somehow contained in the "install" folder, which only contains one file: a large .fuse_hidden0000000400000001 file. |
yeah well looks like its more of a wubi issue than a grub2 issue. I re-read syg00 post on grub2 and wubi.
IMHO you have only windows installed to the partition....then your windows bootloader has an option to boot a single file on the windows partition that is a "virtual" linux http://linux.about.com/od/dist/gr/dstwubi.htm The problem is....grub2 is NOT installed in MBR or in the partition boot record so normal command modes will fail IMHO. 2) I don't blame you for being conservative and trying out linux. Instead of wubi can I suggest you download the windows version of virutualbox and then you can boot up windows...open virtualbox....install any linux distro you like into it....and play with it? 3) other suggestions depending on your risk profile....get rid of windows....install linux....install linux virtualbox and run windows from that if you need something? b) wipe the drive with a linux cd....partition it for real....install windows....into partition 1 = c.....install linux into partition 2 ....partition 3 is windows swapfile and partition 4 is linux swap.....assuming you have a msdos partition table and not GPT When linux installs....install grub2 into MBR and let it chainload to your windows bootloader. |
