It's an odd issue, i installed Ubuntu 11.04 trough Wubi yesterday,it actually worked unlike the last time i tried to when it didn't boot at all.
But there is one thing that bugs me, see, i have 2 HDD's ,a 320GB one with Windows 7, and the other, a 500GB HDD with Ubuntu 10.10.
I have partitioned the 500GB HDD, and contains a NTFS partition, and a EXT4 plus the Swap partitions.
The 320GB is not partitioned, as it only has Windows 7.
Since i installed Wubi on Windows 7, when i have my Ubuntu drive connected, Wubi won't boot the installation, giving me a "no wubdir" error.
However, if i phisically unplug the Ubuntu drive, then Wubi boots just fine.
So, how is the Ubuntu drive interfering with Wubi, to the extent of Wubi not even working when the drive is plugged?.
