Errors When Updating To Windows 2000

[shof515]

I have an old Gateway computer that is a Pentium 3 650mhz with 192mb of ram,right now it is currently running Windows 98 SE and whenever i try and update/do a clean install i always get errors when it comes to copying the files.

The error i get is an error message that says it cant read the file off the cd disk,but the cd is in the drive and this happens alot
