OK, heres what I want you to do...
Go to the link below & download the Windows XP system setup disk (single floppy disk version)http://freepctech.co.../files010.shtml
When you have it, insert a blank floppy & double click the wxpboot.exe file you downloaded. This will create a bootable floppy.
Next boot up your system with the floppy inserted (NB you may have to change the boot priority order in the bios first, to set floppy disk as the first device to boot from)
When its loaded, from the A> prompt, type fdisk and press enter.
If it asks you about large drive support & ntfs, answer Y to both.
In the menu screen, select option 4 to view the drive.
You will see column headings such as partition, status, system etc
Look at the first row underneath these headings & let me know if you see a capital 'A' under <status> heading.
Also let me know whats listed under the <partition> heading & under the <system> heading
Fdisk will ask if you wish to view the logical drive info, answer Y.
You should see one or more entries here, again let me know what is listed under the partition & system heading. (there won't be a status heading)
Press ESC to quit fdisk, remove the floppy & shutdown the system.
Sorry if this sounds rather complicated, but I promise it should all make sense when you actually go to do it.
