Home » How-To: Fix STOP 0x0000007B on installations

Recently I was given a Dell to fix. The Dell wouldn’t boot into Windows with ‘Bad_Pool_Caller’. A few hours of head scratching and data backups later. I decided a reinstallation was the only option. So I blew the dust of my XP Pro CD, only to be greeted with another ‘stop’ error on installation! STOP 0x0000007B(0xF78DA63C,0×0000034,0X x0000000,0×0000000

However, this was quite an easy one to fix.

In the Bios there is an option for either RAID Auto/AHCI or RAID Auto/ATA, the setup didn’t seem to like the AHCI option and required switching to ATA before it would work!

1. On start up (Dell logo), press F2 to enter BIOS

2. Expand the “Drives” section

3. Go to “SATA Operation”

4. Change this from “RAID Auto/AHCI” to “RAID Auto/ATA”
