"BootMGR is missing"
"Press Ctrl+Alt+Del to restart"
Found on the web....
" When you start boot up Vista system, and encounter the following error message, you have probably messed up the important system files and landed in great trouble:
BOOTMGR is missing. Press Ctrl+Alt+Del to restart.
The error happens when you delete, accidentally or intentionally vital Vista system files........ "
The error is probably the same for Windows 7.
Your Vista installation is messed up, probably in this case caused by data corruption.
"About 2 mins into installation i got an error stating cannot read drivers from source."
You should NEVER have a problem reading files from the Windows disk while running Setup, if it's an original disk, and it's clean and has no major scratches.
If it's a copy, a CD-R or DVD-R should read fine, but another type of burned disk may NOT read fine in a drive it was not made in.
When you DO have a problem reading files from the Windows disk while running Setup, it can be caused by a problem the optical drive is having reading the disk, and/or a ram problem .
The laser lens on your optical drive may be dirty. Eject the tray for it - usually you can easily see and clean the laser lens on a laptop with a tissue or a clean soft cloth when there is no disk on the tray.
Or - use a laser lens cleaning CD. If you don't have one, most places that sell DVDs and CDs have them, or even some "dollar" stores have them for a buck or two.
"i tried Vista installation, it got detected and then when i got to advanced option screen.....there were no Harddrives or media sources!!!!!)"
"I checked it out online and the told me to try formatting the drive ( i took it out and connected it to another computer and tried formatting there, it took about 15 mins formatting and then told me formatting was uncessfull. "
"I tried it in disc management and i was told formatting cannot be completed!. when i checked back the status in My Computer, the harddrive had no space allocatons! (the harddrive is partitioned into 2) and both had zero space available. "
If it quit formatting before that was finished, that indicates there's something wrong with the hard drive, and/or, usually, something wrong with the connection of the ram in it's slot(s).
When you're formatting from the disk, the formatting program loads into memory and the the disk is not accessed until the formatting finishes or the formatting program quits.
".....i tried it back a couple hours later and believe it or not both partions were able to be formatted!!!) "
You have a ram problem, and/or your hard drive may be failing !!!
Rule out a poor connection of the ram in it's slots.......
See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
For a laptop, or netbook, you must remove both its main battery and AC adapter before you do that.
For a brand name computer, see the Owner's or User's manual if you need to - how to remove or replace the ram is usually in that - it may already be in your installed programs. If you can't get into Windows, it may be on a disk that came with the computer, or you can go online and look at it or download it - it's in the downloads for your specific model.
Try a memory diagnostic utility that takes a lot less time to run a full pass than memtest86 doe - this one is pretty good - Microsoft's Windows Memory Diagnostic:
It can be toggled (press T) to do a standard or a more comprehensive set of tests - use the default 6 test one first - if it passes one pass of that, use the latter one. A few of the tests in the latter set are intentionally slower.
If you don't have a floppy drive, see the Quick Start Information at that Microsoft link for how to make a bootable CD of the Windows Memory Diagnostic (you need Windiag.iso - you don't necessarily need to use the program they mention).
NOTE - if the ram fails the diagnostic tests, that does NOT necessarily indicate it's"bad" ram ! If it's not the original ram, it may be incompatible ram !
If you DO get ram errors, try re-seating the ram and trying the diagnostics again.
If you STILL get ram errors, remove the ram and tell us the brand and module part numbers on them - either the HP part number, or the ram manufacturer's part number.
After the ram passes the ram diagnostics....
Check your hard drive with the manufacturer's diagnostics.
See the latter part of response 1 in this:

Hard Drive Diagnostics Tools and Utilities
If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best drive compatibilty, on another computer if you need to.
If the hard drive itself tests okay, any data problems found can be fixed, one way or another.
