Windows 98 hard drive not found

[Makemonie]

Hello everyone. Yesterday I was able to get on my PC...but today when I tried to log on...I get a error message hard drive not locate please insert backup disk. So I insert backup disk and I get the same error message hard drive not found/located. I am using Windows 98. Any help would be appreciated. Thank you.

Made changes to your HDD?

If not, it may have failed. Check to see if it is properly set in your BIOS and if all the cables/jumpers are still connected.
