Windows 7: New W7 Pro installation won't start ?

New W7 Pro installation won't start ?

Posted previously to crashes/degugging group...but didn't get too far...

Is there a way to start a Windows 7 system to the C: prompt ? Neither Windows 7 regular start up...or any of the Safe Mode startups will work ? All safe mode starts end at same place with same system file loading and the "...please wait"...except the "advanced repair" which does not solve problem ?

Thanks, Tim

It sounds like something corrupted your install. Since you cannot run a repair install unless you can get into Windows, I would try some things.

You might try removing the secondary display.

Boot to the Win 7 DVD and go back to the repair section-command prompt.
Type slmgr -rearm just in case it is related to an expired evaluation period. I am not sure this command will run this way, but if not post back. I also do not know if this will mess with your activation.

Next try some of the following, although most of these should have been done during the startup repair operations.

Hit enter after each, but type:
SFC /scannow <--will take some time
bootrec /fixmbr
bootrec /fixboot

If normal boot still not possible, you might also try:
bootrec /rebuildbcd

And I don't really think it will help, but maybe go into the bios and change the OS from Plug and Play to no. Change back later.

Have you changed the drives or drive order in the bios, if you have 2 drives?

There are some third party partitioning software you might download and burn so you can boot to one of those and check the drive and its condition. GParted and Partition Wizard seem to be used quite a bit.

Thanks...tried all the Command Prompt files...but nothing changed...then it dawned on me that the problem pretty much must be with the boot.ini or whatever...the prompts you gave me reported Windows I think as the "X" drive...and the scans run before as suggested in Crashes/Debugging via DVD boot/repair reported the Windows disk as I think N: drive ?

So...I opened the box and disconnected everything except the C: DVD's (2) and no data drives (2 Sata non-system drives)...and PRESTO...Windows & booted up normally !!

Now...there's still and issue...added DVD drives one by one and problem...added one Sata problem...but when I added the last Sata Drive ( Sata 3 I believe) then I got the frozen Windows logo screen as before...

Closed down and disconnected last Drive (Sata 3) and Windows again boots normally.

Not sure why the problem seems to be with Sata 3...but will post back if I figure it out...

Thanks for the help...

Does your motherboard have 2 SATA controllers, one for the first 4 and one for the last 2?

Is another driver needed for the second controller, and do you have it turned on in the bios?

To test, you might take the 3rd SATA drive and connect it to one of the other cables to see it it is the drive, or the SATA controller.

On my system, the last 2 SATAs are used for eSATA.

We know now that either the drive or the SATA port is giving you trouble. The latter is unlikely, so try moving the drive to another channel.

Thanks guys...going to have to look this up...brand new MB...but I recall that there are 2 'sets' of Sata connectors....I think 1-4 and 5-8...might be 5-6 ? but I will double check...

Already thought about switching cables/connectors...but this system was working fine for about a week before problems started up...will go thru the MB manual and repost...

Do have Speccy...will run and Windows 7 group system specs are not the problem computer...will run Speccy on that system and post back...

Sounds like SATA3 somehow got marked active and might contain a System MBR that's derailing the boot. Happens a lot here.

You can check this by booting free Partition Wizard bootable CD with all drives plugged, rightclick on any data drive marked active on SATA3 to Modify>Set to Inactive.

Now restart Windows 7 and post back a screenshot of your full Disk Mgmt Drive map, using snipping tool in Start Menu, attaching file with paper clip in Reply box.

OK...downloaded iso...before I start tho I want to post one more item...Windows Disk Manager does not now show the C:\ drive...(main Win 7 installation)...only the 1st data storage drive and the DVDs ?

Both Seagate(Acronis)Disk Wizard and Easeus Partition Master show the C:\ and System Reserve partition for Windows 7.

None of any of the three above is/are marked "active" ? 3 screen shots attached

Should I proceed with Windows Partition Wizard bootable CD ?

You said you have a HD which blocks Windows 7 from booting if it is plugged in. It needs to be checked from boot by Partition Wizard to see if any data partition on it is marked Active. If so, rightclick Modify>Set Inactive.

With data drives unplugged, Try running a Repair Install

OK..decided just opening bootable CD was no real problem...opened by booting to DVD...the troubled drive did show up...but as the #2 drive...not #3...

The troubled drive ..#2..was NOT marked as active...the only thing I noticed was that the first partition was marked as "Primary"...where as the other data drive (real #3) was "Logical" ? ( did not change anything )

The only operation I ran was to label the C:\ Volume as the Main Windows 7 Drive...the label was empty (although before this all did have a similar label indication it was the main Win 7 Installation)

Now the weird part...rebooted and removed DVD as main boot group and set to HDD's...Windows 7 started up normally as if nothing at all had happened...appears to be running well with no new issues or problems...all three drives are accessible...BUT...the C:\ drive still does not show up in Windows Disk Manager....but does again in Easeus and Seagate .
