The problem of dual booting of vista and XP, ask for the speed of the high person to help.

Vista first and then XP is definitely not good.

You can install XP on the C drive first, and V on the D drive later.

In this way, both systems can enter.

It should be noted that after entering Vista, the partition where V is located becomes the C drive, and the partition where XP is located becomes the D drive.

This means that which system you enter, and which system is located in the partition will become the C drive.

Be careful not to get me wrong.

You've hidden one of the partitions, and you're trying to see if it works.

No pirate will be investigated! (Exchange of experience and sharing of resources.)

Steps (1-12) step-by-step elimination:

1.Clean up system debris, junk and registry with 360+ Optimizer or Super Bunny!

2.Too many programs are open.

Memory is heavily occupied.

Run msconfig to close unnecessary programs or use 360 process management (machine card).

3.Determine the graphics card.

There is no problem with the driver of the sound card and other hardware (you can ** drive the wizard to update the driver) (game card) 4The system runs for too long, junk files and registry files are too large, and there are too many DLL registrations.

The solution is to reinstall the system.

5.Reboot or boot press F8 to boot safely.

Restore the last correct configuration (computer failure caused by power failure) 6.If the memory or graphics card is loose or needs to be dusted, use an eraser to erase the gold finger and then install it (blue screen) at a temperature that is too high to see if the fan is working properly or replace the high-power fan.

8.There is a compatibility issue with the hardware and software, and the BIOS settings are incorrect. Restore the BIOS to default.

9.Hard disks have logical or physical bad sectors that can be repaired with efficient source repair tools.

10.The power supply voltage is unstable, replace the larger power supply with more than 300W.

11.Open the case and check if the capacitors near the CPU are bulging or leaking. Leakage.

If there is a suggestion to replace!

12.If it has not been solved, it is recommended to clean the inside of the machine thoroughly, and unplug everything that can be unplugged and cleaned.

Gold finger interface, etc., to keep the inside dry and clean!

The above is only a simple fault reference, thank you, please choose.

Two cases: the desktop launches the program error, and the second case: the program loads incorrectly.

Solution: It is possible to reinstall the system. But it's too much trouble.

You can enter safe mode.

Right-click on my computer--- Properties--- Advanced --- Startup and Failback --- settings--- uncheck box for self-restart.

Then go into the system and if it doesn't reboot, then look at the Event Viewer. What went wrong.

You can give it a try.

If you find it helpful. Please tick. Thank.

It may be that the boot file of the XP is corrupted, and if the XP is not backed up before installing Vista, the XP may never be able to be uploaded again.
