Perpetual Reboot for Failed Win 7 Upgrades from vista

[septprince]

In certain scenarios, a failed Windows Vista upgrade to Windows 7 can throw the computer into a perpetual cycle of restarts, Microsoft informed. The Redmond company did not offer specific details on the causes of a Vista to Windows 7 upgrade failure, but it did offer a workaround for end users affected by this specific issue to put a stop to the continual reboots. The KB article Microsoft supplied for this issue was published after the RTM of Windows 7, and it indicates that the problem impacts all editions of Vista RTM, SP1 and SP2.


“When attempting to upgrade from Windows Vista to Windows 7 the upgrade attempt may fail with the message “This version of Windows could not be installed, Your previous version of Windows has been restored, and you can continue to use it." However, the next reboot of the machine will launch the upgrade process again only to fail with the same message,” the software giant informed.

More then likely a great deal of that will tend to be seen on premade systems rather then on custom builds where most would automatically plan a clean install of 7 from the start. It's still a good one to post here!

Fortunately, it only happens "In certain scenarios"...

The more I read the link, the 'stranger' it becomes...
Perhaps because its written in "Springlish"?

“Windows Vista will have been restored on the computer but the Boot Configuration Database (BCD) store has not edited to restore Windows Vista as the default booting operating system,” Microsoft stated. “The computer will continue to boot to the Windows 7 Setup and then fail until the BCD database has been restored to its previous state.”

AFAIK, BCD store is not an executable, and cannot edit nutthin.
MS calling it a 'database' tends to affirm my limited knowledge.

The solution is: Vista, executing the Vista command:

X:\boot\Bootsect.exe /NT60 All

which is, generally speaking, one of the Win 7 'cure-alls':
Writes the: (in Win7_words: Vista or later) boot sector, blah-blah...

So, TMALSS, V_Bootsec.exe is modifying the file 'bcd' database differently from the Win_7 mods, which are obviously NG.

Anybody know the specific differences?
Is the 'GUID' the culprit?
"Inquiring minds would like to know", and metoo.

Under certain circumstances usually temporary from the start until MS fixes a problem with any new service pack out some have run into problems installing SP2 or 3 on XP as well as the two SPs for Vista. Without any hardware faults most often a failed upgrade generally proves itself to be a user error in most cases however.

This one is no user error - its a flat-out "Bug"...

I got the same problem when I tried using an upgrade disk to upgrade from XP to Vista.

I got the same problem when I tried using an upgrade disk to upgrade from XP to Vista.

That would simply point out a more commonly seen problem when going to upgrade from one version to the next without it being tied to one version alone namely Vista or 7. I can imagine similar if not the same was seen when upgrading from 2000 to XP at times.
