SP1 on stage 3 100% then reverts???

I have tried to install service pack 1 five times with the same out come each and ever time. I've done the drivers and I think that they are signed and the updates are up to date. I have checked their history and the ones that did not install or were canceled have been reinstalled. There is no error number. After stage one and two have run their course and the PC just reaches a point at the end of the SP1 install, where it's rebooting and the % of install is all the way up to 100% it grinds for 4 or 5 minutes and then says on screen "SP1 install failed - reverting changes" and spends the next hour rebooting and undoing all the changes it made. The rig is a AMD duel core 5600 with 3 gigs of ram and phoenix bios. If I need to get more specifics I'll have to get it when I'm on my rig at home. Any help would be appreciated. I obviously need it.

The latest drivers sometimes foul things up more than fixing them - uninstall the drivers you have installed and see if SP1 will install - also note and make sure *all* Vista updates show as being successfully installed - a failed update somewhere wayyyyy down in the list could be causing you headaches....

I was getting the same behavior before I updated my drivers. Do you mean go back to all native windows drivers? and I did go wayyy-- back and checked numbers on updates to make sure thoes that failed had been installed at a later time I'll do that again to re confirm. This is really starting to get the best of me. Each time I try to install the SP1 It takes longer to revert and boot. This last time well over an hour and a half just to boot and then an other 45 minutes to start up after the log in screen. Thanks for the time and help. Any thing else you can think of would be appreciated. Darell

No, I mean uninstall your drivers (if you really want to troubleshoot it uninstall 1 at a time and then try SP1 and see which one causes it to fail - but that will be extremely cumbersome).

Most times when you uninstall drivers Vista will either not be able to use the device or will install la generic driver that is included with Vista.

Well then, I'll give it a go and see if it shakes out. Once again thanks for the time. One question though assuming that the sp1 does install when I go back into device manager to reinstall the updated and signed drivers will windows have saved the copies and roll forward to the ones I had before I uninstalld them?

No, you'll want to manually download and install the latest drivers - forget about Windows keeping drivers, in fact, when uninstall the devices in Device Manager, make sure to select "remove driver" as well so Windows doesn't try to automatically reinstall the driver on reboot.

Oh, and yes - reboot after uninstalling drivers. Vista will then use its generic drivers (install them) and all should be well.

I'll try it tonight when I get back to my home rig. Thanks I'll let you know if we did good!

Hi dedet,

The best time to install a service pack is on a clean installation. If you think about it, the DVDs of Vista with SP1 integrated are just the same as the originals except that SP1 has been slip-streamed in so that it installs along with Vista at the same time. The same was true with XP SP1 and XP SP2 (I'm not sure whether it will be with XP SP3).
The ideal solution is to download the standalone version of SP1 (link given below), burn it to a CD, and then perform a complete clean installation of Vista (remember to back up any data first). Always disconnect from the Internet whilst you install Vista. When Vista has finished installing, now is the time to install SP1. By doing it this way, you should have a greater chance of success because the registry and other important system files haven't become corrupted due to other programs you have (un)installed. When you have successfully installed SP1, remember to install your anti-malware program BEFORE going back online, and make sure that you run a manual update on this and Vista itself before you do anything else.
I notice that you have a 32-bit version of Vista. As a bonus, SP1 for Office 2007 is also available, and this will fit on a standard 700MB CD together with SP1 for Vista (links below).

Hi Dwarf, in revue to make sure I have this in the proper sequential order. Anti-malware program BEFORE going back online, then hook up and go on line manual up date on it and Vista and I'm off to the races? This all sounds doable and I'll give it a go this PM. Thanks for the impute and advice as well the tip on the office update. Darell

Hi dedet,

Yes, that is correct. Hopefully, you should have your system back up and running, together with SP1, by the time you read this. Please let us know how you got on as this will probably help others who are having difficulty in installing SP1.
