Lose 99 Go on my Hard Disk !

Hi

I've just installed Acronis OS Selector 8.0.
So, it resized my Disk (I remembered that there were something like Disk 0 / 141.0Go -> 141.0Go).
Then I rebooted and I saw that my disk space had falled from 99Go Free space to ... 17Mo Free space !

Then, I paniqued ( ), and I have uninstalled Acronis OS Selector.
But there were no more Free Space, I stay at 17Mo free.

And when I check how much space all my files on the Disk take, I see 22,9Go.
So, normally there would be something like 99Go Free, like before I installed OS Selector.

So, what can I do to retrieve my 99Go free space ?
Thank you a lot !

PS : I'm on Windows Vista.
PS-2 : Sorry for my English, I'm French

 

Can you post a screenshot of what Vista's Disk Management shows for your drive?

OSS 8.0 is not Vista compatible (version 10, build 2,160 can hardly be called that). Did it boot into Vista okay?

Why did OSS 8 resize the disk? Did that version have to create a special partition for its files?

 

Hi
Thank you for your fast answer.

I solved the problem !
I simply made a Scandisk (on Vista's Disk Management, right clic on your Disk, Tools, Scandisk) with the automatic fix activated.

It takes something like 35 or 45 minutes to Scan it, and when I rebooted, the problem had been solved, and I also win some Free Space (I were near 99 Go before installing OS Selector, I am now near 114 Go after Scandisk).

Thank you for your support, I hope this solution will help some people
