unable to boot laptop

I am unable to boot up the laptop because of an update. It's not my laptop but I mainly use it. The person who owns the laptop never made backup disk and the laptop didn't even come with any. I can't do anything other then watch a black screen. When I try to do the system recovery, I get a blue screen. When I try to do anything else like safe mode, debugging, etc. I still get a black screen

The Vista recovery disk is used to boot Vista when it won't boot - to run Startup Repair, System Restore, access a Command Line, Recover using a Vista Backup Image, etc.
System Recovery Options. Choose an option tht will not cause you to lose your stuff.

If Vista will not start now, boot the Recovery CD to run Startup Repair which automates System Restore as well as numerous other tests including System File Checker which can repair system files which are not corrupted beyond repair.

If Vista still will not start, try booting into Safe Mode to run sfc /scannow to repair System files.

Below is a bulletin distributed by MS to explain the start up procedure when Windows will not boot.

• Startup Repair. Startup Repair is a Windows recovery tool that can fix certain problems, such as missing or damaged system files, that might prevent Windows from starting. Startup Repair is located on the System Recovery Options menu, which is on the Windows Vista installation disc. If your computer has preinstalled recovery options, it might also be stored on your computer's hard disk. For more information, see Startup Repair: frequently asked questions and What are the system recovery options in Windows Vista? If your computer does not include Startup Repair, your computer manufacturer might have customized or replaced the tool. Check the information that came with your computer or go to the manufacturer's website.
• Change restart settings in safe mode. If your computer is stuck in a loop where Windows fails, attempts to restart, and then fails again repeatedly, restart your computer in safe mode and select the Disable automatic restart on system failure checkbox. For more information, see Advanced startup options (including safe mode).
• Reinstall. If no other options have solved the problem, and you are sure that your computer's hardware is functioning normally, you might need to reinstall Windows. A custom (clean) installation of Windows will permanently delete all of the files on your computer and reinstall Windows, so only use this option if all other recovery options have been unsuccessful. After the installation, you will need to reinstall your programs and restore your files from backup copies. For more information, see Installing and reinstalling Windows

nothing works. how do you do a clean reinstall if the laptop doesn't boot or if I don't have any type of disk

my laptop is Vista and F11 is my system recovery. Plus I have said that once I try to go to the syytem recovery, I get a blue screen. I can't get passed that either. I have even tried it in safe mode. when I try safe mode, it says windows is loading files, please wait. I waited like 2 hours and nothing

OK
From this ISO burn a CD, then install on your computer. If it does not boot, post and we will reset the boot priority. You will need a product key number.

do it have to be on a CD because I dont have CDs large enough for it. I don't know what else to do

You can try on a usb. thumb drive

well I would need to find a USB drive big enough. The ones I have is not even 1 GB. Is there any other way I can fix this, if not, what should I do

I know of two ways, the restoration partition and burning a CD

I'll try another time because I don't have a big enough USB or CD/DVD to use for the burning

CDs are so very cheap

what is the best type of disk to use. I dont want to get the wrong disk

DVD-R and DVD+R discs are best with the procedure.
May I suggest that you try to borrow one from a friend. You will have to buy several as they are not sold alone and there is no guarantee that this procedure will solve your problem. Sometimes it takes several attempts using different methods to resolve a problem such as this one.
