if Vista was on C: and now C: has no NTFS, is it gone for sure?

the good news is, if I go to "/"

and view its "Property"

then it says content is 497GB... which is the total of my C: drive and D: drive...

does that mean my VIsta is still "some where"

but the possible bad news is, it says free space is 210GB....

before installing Ubuntu, my D: drive was full (250GB). and my C: drive was about 235GB full (out of 250GB).

Yes Vista is gone...!

Hello,
According to this you have 3 discs.
2 250GB discs and 1 300GB disc.

The primary disc, the first 250GB disc, is the disc you installed Ubuntu on.

Your second disc, the second 250GB disc, is a NTFS partition

Your 3rd disc, 300 GB disc, has an NTFS partition as well.

If Vista was on your primary disc, then unfortunately you did install over it.
