Okay.
I am posting from a Ubuntu 8.04 Wubi install to Windows Vista Home Basic.
It took maybe an hour or so. Did it work? Obviously, yes (so far
). Was is flawless? Frankly, no.
Since being put on notice there may be issues I was careful with the installation.
I unchecked loading of startup items with "msconfig" and rebooted.
I ran defrag and rebooted.
I inserted the Ubuntu 8.04 live/install CD. I chose to start it and approved it in UAC. I choose to install to Windows. This process was fairly quick. It checked md5sums and installed, then asked me to reboot.
Wubi added a Ubuntu option to the Windows Vista menu but did not overwrite GRUB in my MBR. Points for that.
When I selected Ubuntu in the Windows menu I was presented with a blank (actually very light blue) screen. My hard drive light would flash and then be quiet for a while, flash and be quiet for a while. It did this to various degrees for some time. Towards the end my monitor flashed black a few times returning to the light blue screen. The light on my optical mouse flashed. Then it sat silent with only the light blue screen. CTRL-ALT-x (1-7) were the same. Minus points for this.
I did a cold reboot and chose Ubuntu from the Vista menu. I was greeted with the Ubuntu startup screen and Ubuntu started. So it worked, points for that.
When doing network configuration I had to click on "unlock", then enter my password before I could continue.
I told Wubi to install to 5GB. "df -h" reports I have 2.1GB in use and 2.1 GB free.
