I have a problem that is doing my head in, i ran windows upgrade and next morning my computer (toshiba satellite) had crashed, on start attempt i got the blue screen and it attempted a restart, this just goes on and on. I disabled restart and the blue screen remains.
I cannot boot in safe or any sort of safe mode, still get blue screen

I also had a problem previously with my disk drive not reading disks so cant boot with a disk.


this is the text from blue screen

A problem has been detected and windows has been shut down to prevent damage to your computer
an attempt was made to write to read-only memory
blah blah bla the usual stuff.


technical information:

""" STOP: 0x000000BE (0x826C0354, 0x02F7B121, 0x8039977C, 0x0000000B)

""" iastor.sys - address 826C0354 base at 82605000, datestamp 45d0d237

collecting data for crash dump ...
initializing disk for crash dump ...

I have a SUSPICION that the updates tried to install and there was no room for them . (my drive is pretty full)

I have bought a download of windows 7 and was wondering if there was any way i can install it over the VISTA, using usb, i have tried but it doesnt boot, maybe i have the files in wrong format as they seem to be in BOX ? files.......im getting more and more confused and would be APPRECIATIVE of any advice from you guys.

thanks beforehand.

0x000000BE: ATTEMPTED_WRITE_TO_READONLY_MEMORY
(Click to consult the online Win XP Resource Kit article.)
A driver attempted to write to read-only memory. Commonly occurs after installing a faulty DEVICE driver, system service, or FIRMWARE. If a driver file is named in the error message, try to correct the problem by disabling, removing, or rolling back the driver.
