WinXP does not recognize GPT disks and cannot read and write data on GPT disks, but is not affected when remote sharing.
We can go to "Disk Management", right click on the disk model below, see the pop-up menu, if there is "convert to GPT disk" words, your hard disk partition is MBR mode, if there is "convert to MBR disk" word, your hard disk partition is GPT mode.
However: If you install a Win7 (no matter 32 or 64 digits), your hard disk partition must be MBR mode.
If you have a 32-bit Win8 installed, your hard drive partition is still MBR mode.
Only if you install a 64-bit Win8, your hard disk partition may be GPT mode.
If your computer has two hard drives, you can do a GPT MBR to the WIN7/WIN8 system directly, and if you have only one hard drive, you can go into the WinPE for a GPT disk MBR disk.
Under the WIN7/WIN8 system, press the shortcut key "Win+r" to eject the running window, and then enter "CMD". WinPE opens a command-line prompt in a similar way.
Press the shortcut key "Ctrl+r" to eject the Run window and enter "CMD"
Enter "DiskPart" directly in command line prompt mode!
Enter "DiskPart" directly in command line prompt mode
Enter "List disk" in DiskPart and enter "Select Disk 0" (note: not necessarily 0, maybe 1 or 2, depending on whether 0 is a GPT disk).
Then enter "clean" (Clear all the disk partitions).
Finally, type "Conver MBR". The task is complete, you can according to the past experience to help put xp/win7, etc. into this has been converted into MBR disk.

If too troublesome, can also use Diskgenius tools to convert GPT to MBR, but this function belongs to the charging function (but WinPE general integration Diskgenius crack version) ...
