After installing GPT Loader, Windows XP crashes into BSOD

Scenario: you install GPT Loader on a Windows XP system and restart when prompted. On startup, the system crashes into the “blue screen of death” and you’re forced to restore it without the GPT Loader

Known cause #1: using the FAT32 filesystem. This is guaranteed to happen when Windows XP is installed to a FAT32 partition. For the safety of your data, it’s highly recommended to switch to NTFS (the default Windows filesystem). If you can’t, do the following.

1. Download this file: http://ftp.paragon.eu.com/support/WinRE/install_xp.zip.
2. Install GPT Loader as usual, but refuse to reboot when prompted.
3. Run the install_xp.reg file from the archive and accept the registry changes.
4. Reboot.

After that, the system should be functional.

Known cause #2: driver conflict. Certain kinds of programs that operate on the disk level install their own drivers. This includes backup & recovery software, disk “optimisation” tools, and even some antiviruses. To find out, check a particular registry key.

#1. Launch the registry editor: Start > Run > regedit.

#2. Navigate to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Class > {4D36E967-E325-11CE-BFC1-08002BE10318}.

#3. Check the UpperFilters value. It should only contain PartMgr (a default Windows driver). If it lists other drivers, they likely conflict with our gpt_loader driver, causing the BSOD. You need to find out which software this driver belongs to. Unfortunately there’s no simple way to resolve driver conflicts, so you’ll need to decide if you can uninstall that software to be able to use GPT Loader.
