A few days ago my computers hard drive died. No idea why but it just stopped working. I went out and bought a brand new hard drive at best buy and went home to install Windows Vista Home Premium. Everything runs fine up until it gets to "Expanding Files" around 26%. Once it gets there it just goes to the "Blue screen of death." I'm using a burned iso of Vista x86 to install it(That was my old OS so I just used the serial code I had.) I've tried installing it 3 times now and no luck.

Now when I turn on my computer it will say "Press any key to boot from CD or DVD and BOOTMGR is missing. Press Ctrl+Alt+Del to restart" I made another disc and burned it at a lower speed and still happened. Anyone know whats going on?

Computer specs.
CPU - AMD Phenom 9750 Quad-Core 2.40GHz
Installed Memory - 8192MB/PC2-6400(2048/DDR2 SDRAMx4)
HDD - WD Caviar Green 500GB SATA

Or just look up HP M9400F.

(Hardware I took out because I thought was making it do this)
NVIDIA GeForce 9800GT
Killer Xeno Pro Network Card.

Doesnt sound like theres anything wrong with the install disc and it would reject the key when you type it in if it was that, and its unlikely to be the hard drive, sounds more like theres a problem with your ram, go into bios and check the timings are the same as those printed on the ram sometimes the bios will load the wrong timings, if they are ok take ram out and try one stick at a time in the different slots one of the sticks has probably gone down.
