wubildr.mbr missing or corrupt

Question

I'm dual booting W7 and Ubuntu (installed from Wubi). I've had it up and running a few times but today I'm getting a message from Windows Boot Manager when I select Ubuntu that wubildr.mbr is missing or corrupt. Any help would be greatly appreciated.

Solution 1

It is a general problem that happens with WUBI.Since Ubuntu is installed to a file inside windows partition,it becomes susceptible to corruptions that generally happen in Windows.You can reinstall Ubuntu but I recommend a full install.

Solution 2

I can't test this but first use bcdedit from an elevated command prompt to find your Ubuntu partition and its identifier. Then try:

bcdedit /set {<ubuntu_id>} device partition=<ubuntu_part>:

@creade So you're using windows boot loader to load linux? as opposed to using grub(2) to load windows?

Is Ubuntu on the same drive as Windows, or external? Are you using anything special on your disk, such as encryption or RAID?

@xenoterracide wubi - is a weird way to install ubuntu - inside big file on windows partition so there's no other options, I guess.

I gave this a shot but the partition was already set correctly in bcdedit.

Have you tried this?

I did a fresh install and it seems to be working fine now.

be careful if the ubuntu folder is on another partition
