Cannot boot after wubi install

[CaKiwi]

I deleted my 9.10 wubi install and tried to install wubi 10.10. Now I get the following messages when booting into ubuntu

Gave up waiting for root device
...
ALERT /dev/sbd1 does not exist. Dropping to a shell

I can boot into windows 7 without problems

I ran the boot_info_script from the live cd and this is the RESULTS.txt file

Any help appreciated

Are you sure you had 9.10 installed with Wubi?

Your boot info script says you have/had grub installed.

You may want to search for the wubi megathread and see if you can find some info in there. I can't seem to find it right now.

[CaKiwi]

I'm sure I did a wubi install.
I originally did a normal dual boot installation but I was continually having problem not being able to boot into windows 7, seemingly after windows did an update. See this thread http://ubuntuforums.org/showthread.php?t=1376746

[bcbc]

It's interesting that your hard drive shows up as /dev/sdb ... where is /dev/sda? If you look at your leftover karmic grub.cfg it refers to (hd0,5) (which is /dev/sda5)

It's probably complaining about /dev/sdb1 because it should be /dev/sda1. You can check this:

1. When you select Ubuntu it goes to the grub menu
2. Hit 'c' and enter ls (lower case LS)
3. If you see (hd0) (hd0,1) (hd0,2) then you should be booting /dev/sda1
4. If so, hit ESC to go back to the menu
5 Hit 'e' to edit the entry. Change /dev/sdb1 to /dev/sda1
6 CTRL+x to boot
7. Drop to terminal (CTRL+ALT+t) and update grub: sudo update-grub

California Kiwi,

Dutch70 pointed this thread out to me.

I have been following the phenomenon of LiveUSB's appearing before the hard drives (LiveUSB is /dev/sda, your hard drive is /dev/sdb) and the issues that cause it.

Right now I am thinking it happens when a hard disk is a little slow to spin up. This MIGHT be what caused Windows 7 to not boot properly from grub on your system. But I am still too early in the study of this to say for sure.

At this moment, I have a working theory; and as a side effect of testing that theory I hope to get your WUBI install working again (The old Win/Win).

The idea is to add a rootdelay to the Ubuntu boot, to give the disk a little time.

Please boot off the LiveUSB, select TRY, and then:

In the Terminal (Menu to: Applications >> Accessories >> Terminal):


sudo mount /dev/sdb5 /mnt


gksudo gedit /mnt/etc/default/grub

change this line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash rootdelay=120"

save the file and exit.


sudo grub-install --root-directory=/mnt /dev/sdb

With any luck, you can now reboot and get into Ubuntu.

Thanks for the replies. I decided to try a full install and it has gone well so far. Maybe it will all fall apart again when Windows does an update, so I will bookmark this thread just in case I have to try Wubi again. I think the wubi problem is related to the fact that I still had an old partition and it got confused over the partition labels.

Thanks again
