How I can install XP SP1 on a laptop?

It is complete format is preinstalled with Vista Business, but I want Windows XP, but not bootable CD with SP2, and if you try with SP1, the error message apears stop 0×0000007e (0xc0000005, 0xF748E0BF, 0xF78DA208, 0xF78d9f08 pci.sys_Address F748E0BF F7487000 3b7d855c timestamp base. Anything I can do to install it correctly?

I do not know if you are installing on top of Vista, but how to install XP is to start with the CD instead of hard disk. To do this, by changing the settings in the BIOS (also called CMOS). This can be accessed during startup, usually by pressing Del, F1 or F2. It's before Vista starts loading. SP1 or SP2 has nothing to do with it booting from the CD. It has to do with the OEM versions and updates. Best alternative is to return to partition the hard drive … It is usually best done with 'fdisk' … a profit of 98 Win. Then do the above … completely erase everything on your hard drive, including Vista. You better be sure you can get the drivers for XP for your hardware. IOW, if the computer "model" used is sold with two Vista and XP, there is no problem. However, if you only sold (and sold) with Vista, it is possible there are no drivers for the hardware inside the laptop to work with XP.

Laptop boot normally, even in safe mode?

I first carried a white and a black screen with options to select Safe mode, last known good configuration and other options. Whatever you choose, Windows will start booting, but then flashes a BSOD with error code *** STOP: 0×00000050 .. then go through the same process over and over again. I tried all F8 options but none seem to work. Also with options like safe mode, etc. It is said that insert the Windows installation disc, restart the computer and repair .. but my laptop has been pre-installed with Vista and do not I have a record! Is there another way to fix my laptop without the installation disk? Thanks: D

Your laptop should have come with a way to restore Windows or a disk or perhaps a recovery disk recovery score. (You may be able to boot from the partition, if you repeatedly press F12 after motherboards the original post) It seems that you need to reinstall Windows. You can always borrow a Windows disc of a person because you must have a label on your computer laptop with the Windows CD Key. If you have important data on the disk that you need to download I suggest you use the method of lending Windows Disk (I'm sure you know someone who has the drive, just to reassure use your own CD key is therefore perfectly legal) In this way, you can make a repair facility to get in Windows to move your important data on a flash drive. Then, reinstall a fresh copy of Windows, because when perform a repair installation of Windows, still clean your registry and provides a new way that their work programs. If you need further assistance, please send an e-mail. Added note: If you use the loan (because the CD to reinstall delete your data without giving you the opportunity to move the laptop), then Use can use the recovery disk or partition for second and fees
