I am working on HP 8260 PC. It had 2 HD's and I took one out. The HD I want to use was partitioned so I ran Fdisk and deleted the partitions, then created new primary DOS partition and made active. I run the Win98 CD and PC boots off the CD and goes into setup to the point that it wants to format the drive. Then I get error message that Windows cannot format the drive. I put the same HD in another computer and sucessfully ran setup. Then transferred HD this computer - won't work- won't boot- says Op Sys not found. Have formatted again in other PC and run Fdisk again - still have same problem when setup wants to format the drive.
