How to uninstall OSS without booting into an OS?

[Pikachuwee]

I recently installed OSS into my computer, but it does not finds any OS!

I cannot boot because of it, I have a Linux Live CD and I have full access to all my Vista/Linux files (yes, I dual-boot Linux).

My primary OS is Windows Vista, any help?

If you created your DD CD with the OSS programs, you should be able to uninstall it using that.

How were you dual-booting before? You could restore/reinstall that boot manager (GRUB, for example).

If Vista is on the Active partition, you could use the Vista DVD to repair the MBR which should allow direct booting into Vista. You'd have to fix your Linux dual-boot setup afterwards. If you do this, boot to the Vista DVD, select to Repair (don't do any automatic repairs), select the Command Prompt and run the following commands (<ENTER> means to press the ENTER key):
bootrec /fixmbr <ENTER>
I don't think you'd need to restore the boot sector, but, if you do, it would be:
bootrec /fixboot <ENTER>

I downloaded the software, I don't have a disc :(

I dual boot Windows and Linux Sabayon, I use GNU GRUB as the boot loader.

That command would reset the boot loader back to the original Windows boot manager?

If you have another computer available, you could install DD, create a CD that includes the OSS programs and then uninstall DD.

You would need to reinstall GRUB. If your version of Linux has a Live CD, you could probably do it from that.

Correct. Those commands would reset the MBR and the boot sector of the Active partition (normally the Vista partition) to the Vista standard. The computer should boot directly into Vista.
