Well, this is the biggest frustration in many days. I spent the whole Thursday installing and reinstalling OpenSolaris and Vista on my laptop. First I tried making it dual boot, but somehow the OpenSolaris install DVD (build 72) kept on having problems during the disk partition phase. So installed build 65 using the entire hard disk. Then restored Vista using backup DVDs. This time, both GParted (v 0.3.4-9) and OpenSolaris build 72 had no problems resizing the partitions and installing on the second primary partition, respectively. That process took the entire day on Thursday and about 8 hours during the following night. Even then, there are issues with GUI login (it doesn’t show the login screen and during later boots just resorts to CLI login.) Since I have a Unix Programming class on Friday morning, stopped experimenting further with the laptop and used the Vista partition with OpenOffice presentations for my class.
I am yet to reboot my laptop and troubleshoot the UI login issue. That would be a good homework for the weekend.
