Here's how things went. I had a machine originally with a Windows 98 system (on drive C), and later I installed a Windows XP system additionally (on drive D). Then I noticed that when using XP, the speed was extremely slow, so I wanted to uninstall XP. I went into 98 and formatted drive D. But when booting up, there was still a choice for two systems. XP couldn't be entered anymore. I wanted to remove the option to enter XP. And I thought of doing it like this:
1. Boot the system with a Windows 98 boot disk. 2. Del C:\boot*.* // Delete all files starting with boot 3. Del C:\nt*.* // Delete all files starting with nt 4. Del C:\hiberfile.sys // Delete the hibernation file 5. Del C:\pagefile.sys // Delete the paging file 6. Sys C: // Transfer Windows 98 system files 7. Finally, enter the command "Fdisk /mbr" at the command prompt and press Enter. But when I used dir to check the files in C:, I found they were all hidden files, and when I used dir/a, I could see them. When I ran del c:boot*.*, it prompted that the file was not found. The above steps 1 - 5 all prompted that the file was not found. May I ask how to delete these files? Besides, please teach me if there's a better way to delete XP? (I found on the Internet saying to use the 98 boot disk, boot up and then run format -ur, but it prompted: parameter format not correct - -ur. Also, using Super Rabbit, but it didn't work. Also, the method I don't want to do, format drive C and repartition.) Hope everyone can give more support.
