    Hello, I need help. I was trying to upgrade my non qualifying laptop to windows 11 enterprise. I have tried many tools but did not succeed.

    I thought maybe I need to repair something so I ran tweaking.com's repair tool. It suggested that i run repairs in safe mode so I followed the advice and also set up a check disk to run at start up.

    Now I can't get the laptop to boot into windows. I did have to use msconfig to set the safe mode boot and the software included the scan before boot.

    I either get an endless boot or an endless "click any key to cancel disk check....within 8 seconds" I have to hard boot in either case. I have a windows 11 disk i'm using to get to recovery. The tools there don't seem to fix the problem. I don't know enough to use the CMD to recover unless it's spelled out for me.

    My laptop has been down for more than a week and i'm stressed over it. Does anyone have time to guide me to solve this or can you recommend a place that I can learn how to solve this problem?

    How old is old? The CPU is i7-7500 I think it's 2017 but it's stuck in a boot loop or a check disk boot loop

    is there a way to turn off the disk scan before boot? it hangs right there and won't allow me to do anything

    can't boot to safe mode with disk scan hanging

    Usually, the disk scan (unless you scheduled it manually) runs only if one of the drives has the dirty flag set (unclean shutdown etc.). Booting with an external WinPE and running chkdsk c: /f /x from there might clear the dirty flag at the end.
    With a normal boot, the dirty flag is never cleared as the process does not run to completion.

    Yes I have important stuff on that laptop. Its my main one. The one im on now is a year older and a generation older cpu but is running 11 enterprise perfectly. It is a lower grade laptop.

    I had software set the disk scan on boot that is looping and never finishing boot. I can use CMD with the 11 recovery environment but don't know the commands to remove that pre-boot scheduled scan

    I haven't thought about reinstalling windows 10. I'll go try that as long as it's not a clean install.

    *edit - now i'm having trouble getting into 11 recovery.

    In place upgrades of Windows 10 to 11 are always a mess and leave a mess behind -- massively bloated (and often corrupt) registry and install size that can be enormously larger than a clean install of the Windows 11 SKU you you're upgrading to...

    You can get to a recovery environment from Windows 10 or 11 install FLASH media just boot the thing and open the command prompt with SHIFT+F10 and run chkdsk as Carlos Detweiller recommends above, then reboot again and if you don't get into Windows normally do the commend prompt thing again and run sfc /scannow.

    Once you're back in action after an episode like this it would be smart to backup your important stuff and do a clean install of what ever OS you intend.

    somehow windows is on drive D not C. is there a way to fix that?

    I tried using diskpart to change the drive letter back to C but it's saying it's not free to be assigned after I changed C to Z to free it up *edit - i was able to rename back to letter=C *edit-upon reboot the drive letter reverted back to D by itself.

    This is what I'm looking at and asking for how to solve it. I used diskpart to fix the drive letter but on reboot it reverts right back to D.

    thank you for the link. so 2021 is the better choice, ok for the troubled laptop. I don't think anything will install now but when there's a solution i'll run that version. Thank you again.. Interestingly, this old laptop is 6th gen running 24h2 26100 enterprise LTSC. It had ioT but i used some app that changed the version and I forgot which app did that so I can revert it back to IoT., I can't find anything wrong with it other than sometimes the graphics look like it's melting and snaps back seconds later.

    i think the partition with the boot information is corrupt or missing because it keeps reverting to D instead of C.. Just a guess. I have to find out how I can fix that.

    This is as far as I got.af least c is still c. I created a 99mb partition for boot but I don't know how to write the boot information inside of it

    I'm guessing here as I wasn't there to follow all the steps and outcomes of what may have transpired, but it looks like:

    · you have a 1TB SSD in this laptop (what make and model is this laptop btw?)
    · less than half of your SSD is actually allocated to a Windows install and in place upgrades
    · you likely have less than 200Gb of 'critical data' on this system to recover unless critical partitions were deleted or corrupted
    · a mess has been made of the standard Windows and/or OEM partition layout by updating and/or recovery attempts

    If these assumptions are correct, not knowing what kind of recovery and or update failure(s) happened here from attempting in place upgrade(s), or any OEM recovery/reinstall preinstalled software and partition(s) that may have attempted their own interventions -- I would recommend you use any number of Windows PE or Linux recovery tools to back up the critical data on this system to FLASH drive(s) before you proceed further!

    The next step, and what OS or Windows SKU I'd recommend (or use myself) would highly depend on make/model of this laptop and how you actually use it -- what applications you need to run, what you do with it, do you game on it, etc..

    Generally after you've recovered your data, I'd use the Laptop's BIOS SSD clean tool to clean wipe the SSD if it has one, or use Windows DISKPART to wipe everything including all partition data to avoid future issues:

    In a command prompt:

    Type "diskpart" and press Enter to launch the DiskPart utility.
    Type "list disk" and press Enter to see a list of all disks on your system.
    Identify the disk that you want to delete all partitions from. Make sure you choose the correct disk, as all data on the disk will be permanently deleted.
    Type "select disk X" (replace X with the disk number) and press Enter to select the disk.
    Type "clean" and press Enter to remove all partitions and volumes from the selected disk.
    Type "exit" and press Enter to close the DiskPart utility.

    Again, depending on make, model, year as well are all the parts in the machine like the SSD and RAM the original OEM parts, did you or anyone else upgrade anything, and what you need and intend do with this machine would determine what OS I'd recommend, and my recommendation will be only that, what I'd install for that use case and I'll offer why...

    I personally would not go any further with in place upgrades or attempt to install on top of existing install(s) and recoveries, as there's too much that can get botched at this point, and you're not going to have a clean OS install with known install parameters that if it gets flaky in the future (which is likely at this point) you and anyone trying to help you is just going to be lost in the woods again as far as what's gone wrong...

    Is there a \DosDevices\C: entry in the MountedDevices registry key?

    Code:
    \\HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

    I'm really guessing that the fact that I had to create a boot partition says to me that I created an empty partition that needs boot information. That is why it was reverting to D instead of C when I changed it. I found a more permanent solution to keep the C designation persistent. My main laptop is an HP Envy. That's all I can tell unless there is a way through CMD to gather information about the laptop
