My guess is that your drive has been formatted to NTFS and is not recognized by your older 95 floppy, which expects FAT. Perhaps, instead of trying to format it, you should try to FDISK it, erasing the old logical drives and then replacing them. If this works, then you have gone to a lower level than the file system and may be able to format for FAT 32. (I have never had to do this, so I do not know for sure that it will work.) FDISK should be on the Win 95 boot disk. If this works, then you should be able to install 95.

It's an AMD Athlon 1.15ghz processor, and I just had a new motherboard installed along with 512 mb of RAM. She was having freeze ups and random rebooting problems. I took the computer to a tech and had the install checked out because it was still random rebooting. Seems some "thermal grease" was not applied and the processor was overheating. Now comes the problem...they installed my Windows XP with a boot disk for NT. Now I can't uninstall XP, which is not needed on this machine because it will only be used for games by my young grandkids. I have down loaded boot disks for both Win 95 and Win NT. Can't get NT boot to work because files were to large for floppy and I can't get the system to boot up to CD. I can boot up with Win 95, but the system won't recognize my hard drive. All I want to do is format "C" drive so I can load Win 95 or Win NT. What am I doing wrong? When I give the command at A: prompt to format c:, it tells me "invalid drive". I am only a novice at this, so any help given would be appreciated and keep the lingo so I can understand...please!!
