i need a lot off help, so if anyone can help it would be greatly appreciated.
i am not a big computer user but i do use my computer, recently my brother tried to install a new version of windows on my computer, i used to have windows 95, and he was trying to upgrade to windows 2000, well in the process something got screwed up, and now it gives me operating system not found when i try to start it up, and now i cant even reinstall 98. can someone tell me what's going on and how, if possible, can i fix my computer.

Do you have the win95 install cd?

Is the win2000 a upgradeR or no previous_os_required?

could buy hardrive software that works with 95, win2000, ...

win2000 needs 400 megsHD +15% Totaldrive size free & 256 meg mem to run hafway decient; and 90+ megHZ cpu.

win95 seems to work better with CDromS then win2k.
windows ME would likey work well with your compter if you have 1 gig free. Cause win ME "breaths" .

HrdDrv software might be able to get the HD usable. For win 95 win2000

or ME
