Why is my laptop getting a blue screen (error code 0×7b) when installing Windows 7?
Laptop’s a Gateway NV52 with Vista Home Premium 64-bit. I’m upgrading to Windows 7 Home Premium. I ran the Upgrade Advisor and it told me to uninstall ATI Catalyst Install Manager, which I did.
I put in the upgrade disk, and after Phase 1 (3 total phases), it had to restart to begin Phase 2. After the Gateway logo screen, it blue screened on me. The error code was 0×7b. It didn’t even do the whole mini dump thing it usually does when it blue screens. It never even makes it to the Welcome scene (where the green bar is loading on the black screen, not the Vista welcome scene)
It happens again when I restart it. The only way to fix it is to go back to a restore point BEFORE I deleted ATI in which case I’m in the same situation where it tells me to uninstall it before updating.
Help?
EDIT: Yes, I’m using the upgrade disk for 64-bit.

Hi there;
That error code means: STOP: 0×0000007B (parameter1, parameter2, parameter3, parameter4)
INACCESSIBLE_BOOT_DEVICE
Basically it has lost its connection to the partition.
I would try this:
Leave the ATI Catalyst Manger installed, pop in the upgrade disk and see if it upgrades. Just a off question but you are using the windows 7 64 bit upgrade disk? If not the upgrade disk for 32 bit will cause the blue screen problems.
Good Luck
Edit:
areful on the format option that is posted, your disk is a upgrade and most likely will not support a clean install. So here is some more info for you to consider:
Stop 0×0000007B (INACCESSIBLE_BOOT_DEVICE)
These two errors have similar causes and the same troubleshooting steps apply to both of them. These stop codes always occur during the startup process. When you encounter one of these stop codes, the following has happened:
1 The system has completed the Power-On Self-Test (POST).
——————————————————————————–
2 The system has loaded NTLDR and transferred control of the startup process to NTOSKRNL (the kernel).
——————————————————————————–
3 NTOSKRNL is confused. Either it cannot find the rest of itself, or it cannot read the file system at the location it believes it is stored.
When troubleshooting this error, your task is to find out why the Windows kernel is confused and fix the cause of the confusion.
Things to check:
The SATA controller configuration in the system BIOS If the SATA controller gets toggled from ATA to AHCI mode (or vice versa), then Windows will not be able to talk to the SATA controller because the different modes require different drivers. Try toggling the SATA controller mode in the BIOS.
RAID settings You may receive this error if you’ve been experimenting with the RAID controller settings. Try changing the RAID settings back to Autodetect (usually accurate).
Improperly or poorly seated cabling Try reseating the data cables that connect the drive and its controller at both ends.
Hard drive failure Run the built-in diagnostics on the hard drive. Remember: Code 7 signifies correctable data corruption, not disk failure.
File system corruption Launch the recovery console from the Windows installation disc and run chkdsk /f /r.
Improperly configured BOOT.INI (Windows Vista). If you have inadvertently erased or tinkered with the boot.ini file, you may receive stop code 0×7B during the startup process. Launch the recovery console from the Windows installation disc and run BOOTCFG /REBUILD

wish I could help more.
Well the only reasons i could think of is that there is something wrong with the CD, Your hard drive has bad sectors or something is not co-operating because of something else. When i installed 7 it wouldn’t boot because of my ipods being plugged in, disconnect everything and then try it. If not put all your programs on a external and format your hard drive and install windows 7 cleanly. It could also be some other program.
The easiest and fastest way to solve this problem is to run a registry cleaner software. A registry cleaner can eliminate errors in your record. This record stores all information about the software, drivers, applications and games that are installed on your computer. And in time, it can get bad, because some obsolete entries are not deleted and can lead to what they call the “blue screen of death.”By using a registry cleaner http://make-computer-run-smoothly.com the blue screen error can be eradicated and increases the speed of your computer in the process. In addition, the blue screen of death will not happen if you regularly check and care for your computer system.
RegTOOL can helps you scan your PC, clean your registry to fix system slow, freezing and crashing in cluding blue screen when installing xp.
