Windows 7: BSOD - Cant boot into safe mode

BSOD - Cant boot into safe mode


I would appreciate any input about this problem.

My set up is or was dual boot Windows 7 rc712 x64 and vista x64 on 2 partitions on the same drive. Suddenly bsod and looped rebooting with windows 7 and I can't even load windows 7 in safe mode. This ocurred after a video crashed in windows 7. I could not load safe mode but I could load vista x64 reguarly(it was a fresh OS I never used). I did a windows 7 upgrade install over the vista when I meant to reinstall on the windows 7.

I had tried to boot from windows 7 disk and couldn't repair the old windows 7 installation. How do I get back to my original windows 7?

Some other babkground info. Prior to all this but maybe unrelated were dreaded nvlddmkm.sys errors even after fresh installs of windows. This error was under my old 32 bit vista right after I changed video cards and occured after windows loads or windows media player opens. My solution was reinstall windows thus I upgraded to windows 7. My orginal windows 7 custom install(not upgrade) still had some errors though not as many errors and I could boot into safe mode, shut down, then everything was back to normal until the next error. XFX(my video card manufacturer thinks it is a software driver issue and not hardware)

Here is the text file created shortly after my first bsod.

Welcome to the sevenforums! cjm18

I think one of the main problems you are having now with that error is from it being a generic error and not a hardware problem. That file name comes up a lot when someone is running an NVida card while those running ATI cards run into the same with a different file name provided. "atikmdag stopped responding" is also what someone was taking note on at nvlddmkm stopped responding and has recovered.

Since the first 7 install was problematic you may simply seen a bad install that needed to be replaced or something simply didn't go on fully. For insuring the best results you may not like the answer depending on how you have the Vista/7 dual boot set up. Which version is on the first primary?

If 7 was installed onto the second primary with the 64bit Vista on the first the solution would be reformatting the 7 primary for a totally clean install of 7 to avoid passing on the problems from the present installation seeing a brand new registry to work with as well. It would seem the present installation is loaded down with headaches you want to get rid of rather then to continue on with.

I'm not at the computer now but I bet vista was and is the primary because it was installed before win7. However I find it odd that installing windows on a fresh drive didn't help. Perhaps I had the old 32 bit vista drive attatched and it copied some settings over.

I now get the error in the win7 that I installed over the vista 64 bit.

Assuming vista was the primary and I want to fix this forever, how do I do a clean install on the original win7 that I can't boot into. It's a 16 gig partition. How do I make it the primary. Use boot manager?

Thx for your help.

I would need to see a screenshot of the disk management view of your drives and partitions there or even a skech at how the drives are partitioned with each labeled to show how you set things up there. Then we can go from there to see things work out rather then seeing any confusion trying to go in two different directions.

The idea would be retracing your steps to find out what will work the best at this point. From there it wiill go a lot smoother in deciding which steps to take first as well as which drive you will want as the host.

The two screens here will show how things looked when the two 7 betas were set up with the previous XP/Vista dual boot across two drives and the present partitioning of course having added another drive in for two separate 64bit RC installs along with the 32bit RC seen on another drive allowing far more drive space for each install to work with.

Here is the screen when booting from new win7 which was vista 64 bit. The 16 gig partition is the orginal win7.

Your second drive there looks like a WD 640gb Cavier model if I'm nor mistaken. The first thing I would advise right off would be booting up with a GParted live cd and shrinking the first primary down a bit to provide more space for 7 to begin with.

Despite the MS "minimum" once you start installing various programs and adding files that tiny amount will fill right up too fast seeing Windows crash having no room left for virtual memory seen in the paging file. Once the first primary there is reduced the time conssuming part will be seen moving the second one back in order to see that expanded. You might just end up seeing the present 7 installation suddenly run again!

With the two storage drives now in here having everything already backed up I would simply reduce the first, nuke the second, and simply see a brand new primary for 7 much larger created for a nice fresh clean install. I've done that enough already for trying out different configurations. Any previous glitched would automatically be resolved.

Your other best option since the second drive is larger then the first would be splitting drives between the 64bit Vista and 64bit 7 with the second partition on drive #2 used for storage. You would still shrink the first down somewhat. But each version would end up on the first primary of each drive(which Windows loves to start with).

A 3rd option is available now as well. You have to consider if you will still be planning to run the 32bit Vista along with the other two or eliminate that from the equation entirely. You could then split the first drive for a dual boot between the 64bit Vista and 64bit 7 and leave the second larger drive aside as a storage and backup drive. Once everything is running good one the first drive between both 64bit editions you could then create backup images using a now free version of the Macrium Reflect program.

Thanks. At this point I don't see a reason for vista at all - I like windows 7. I don't think I mentioned this but the original windows 7 was a clean install but it was installed after vista 64bit. Vista 64 bit was a clean install. I was getting a low disk space error on the original win7 partition.

Yes, the second drive there is a WD 640gb Cavier model. I am not familiar with GParted live cd (looks similar to windows diskmangement) but basically you suggest shrinking the first primary down to like 550gb and then what do you mean by "moving the second one back in order to see that expanded. You might just end up seeing the present 7 installation suddenly run again!" Do I Use the cd to 1) shrink the large partition and 2) expand the small partition? Then it might be able to boot into the original windows 7(small partition)?

"With the two storage drives now in here having everything already backed up I would simply reduce the first, nuke the second, and simply see a brand new primary for 7 much larger created for a nice fresh clean install. " Is it necessary to back everything up if the 16 gig partition(soon to be larger) is the only one that is being formatted(nuked)? Does the CD have that option? I have lots of data stored on the smaller drive. I have 95% of programs installed on the large partition of the WD Caviar.

To show how things look now on the 640gb and how you can reshape the partitioning compare the three images made in paint to the first of the two images early of the disk management to see how the drives looked when split for dual boots there.

Unfortunately you can't write things out in paint so you'll have to excuse the penmanship. The "V" subs for Vista while the "7" is obvious with the first showing how the drive looks now.

The second shows how the 7 primary is moved towards the front of the drive once the Vista primary is reduced in size. The third space in total black is now raw empty drive space with nothing on it.

Now to do what is considered merging partitions the 7 primary once having no free space left inbetween that and the first Vista primary you simply expand the 16gb 7 primary into the empty drive space at the back end of the drive now seen to come out with the third image.

On a 640gb drive depending on how much free space is available on the Vista primary you'll want to leave at least a good 80gb free to prevent running out of room there as well as any new files added onto it. The new look for the 7 primary can easily see 100gb or more!

Unless you have tons of files on the Vista primary you'll want the new 7 theme to provide far more drive space and eventually you won't even want Vista on much longer once you get accustomed to 7! Here after a nice clean install of Vista with SP2 on I created an image to tuck away until the 32bit RC has had it's day with Vista having been the former resident OS there as you can see from the first image earlier.

And for dual booting two versions on two drives each should see all programs installed on it's own primary. That frees up the entire second drive for the next OS which just happens to be 7. The best place for a dual like this would be seeing 7 on the first partition of the second drive even if the drive is split up. The second would simply be a storage/backup partition in the event you end up reformatting either of the other two(Vista or 7 for any reason).

For getting familiar with booting from a live cd version of GParted or the full name Gnome Partition Editor review the information seen at GPARTED DOCUMENTATION - GENERALITIES

Some extra screens are seen at GParted -- Screenshots

For burning a live cd you will want the ISO not zip file download of the latest 0.4.5-2 release available at GParted: Files

First look over the first partition to see how much drive space is used. Once you know the percentage you can go by that to leave plenty of space while still seeing that one shrunk down. Moving a partition back however does take some time. But first read through the documentation.

windows 7 rc7127

update: new video card(7600gt) and no nvldmmkm.sys errors in the new win7 installation but still cant boot into the old win7. I think the prob is the card but ill have a tough time convincing XFX since they think it isnt. No errors during games.

Next I used gparted to shrink the partition but there was an error when enlarging the other parition. repair didnt work so that partition is gone i bet. Its 0 bytes and unformatted in my computer. It's okay, no important data on there.

Booted fine into the new win7. Computer has froze twice though but no blue screens

And a third time. I only had Internet explorer open.

after gparted,windows ran chkdsk the first time I booted back into this new win 7 and found no errors

winload.exe was missing from the old win7 install (after using gparted)
