Why does my PC keep booting into the bluescreen and not let me leave

It shows this

When I try to boot up without my USB stick it pops up with "There is no operating system found"

When I try to do startup repair it says there still not enough space

Thanks for the update, Andrew. That confirms a few key things.

Your PC is likely booting into Windows Preinstallation Environment or partial setup mode.

The C: drive showing only 99.9 MB total means it's not your actual Windows installation partition, it’s probably your System Reserved partition or the recovery partition, not the main OS drive.

Let’s identify the correct OS drive and free space there

> Step 1) Open Command Prompt again from Windows setup USB

Go to Repair your computer > Troubleshoot > Advanced Options > Command Prompt

> Step 2) Open DiskPart and list volumes

Type

diskpart

list volume

Now carefully check the Volumes listed. You're looking for

A NTFS volume (not FAT32)

Around 50–500 GB in size

Doesn’t say 99MB like C: maybe D: E:, or something else

Possibly labeled "OS", "Windows", or has no label

Take note of the drive letter assigned (or we’ll assign one next). If you can also send a screenshot of this would be great.

> Step 3) If it has no letter, assign one

If the correct partition has no drive letter, type

select volume X replace X with the volume number of the large NTFS partition

assign letter=Z or any unused letter like Z

Now exit diskpart just type exit

> Step 4) Clean up space on the actual OS drive

Now access the correct drive

Z: or whatever letter you assigned above

cd \windows\temp

del *.* /s /q

cd \windows\softwaredistribution\download

del *.* /s /q

Then disable hibernation

powercfg -h off

Then check remaining space

dir

Or launch Notepad again

notepad

File > Open > This PC → Confirm free space for your newly mounted drive.

> Step 5) Reboot your PC

Type

exit

Restart and remove USB if it’s set to boot first.

If the system still won't boot:

We may need to run Startup Repair again after you've freed enough space.

Go to Repair your computer > Troubleshoot > Startup Repair

If that still fails, we can do an in-place reinstall without losing files (as long as the OS partition is still there and you don’t format it). Let me know if we need to take that route.

Let me know how it goes.

You're doing great so far, and you’re very close to recovery. I am here if you encounter any trouble.

Every time I type in "powercfg -h off" It shows![](https://learn-attachment.microsoft.com/api/attachments/3245398a-e60d-49a2-a09e-fe0c1296741d?platform=QnA

And also when I type in "cd \windows\temp" It says "The system cannot find the path specified"

It also shows that my System C: has 88.2 MB free of 99.9 MB when I use notepad

Absolutely, Andrew. Thank you for that update. Yes, a C: drive with 0 bytes free can definitely be the root cause of this issue. When your system drive is full, Windows can’t load properly, install updates, or even boot in some cases which explains the recovery loop.

Follow these steps.

> Step 1) Boot to command prompt from your Windows USB

Click Repair your computer and go to Troubleshoot > Advanced Options > Command Prompt

> Step 2) Now type these one at a time

C:

cd \windows\temp

del *.* /s /q

Then clean up more system files

cd \windows\softwaredistribution\download

del *.* /s /q

And clear the hibernation file if enabled

powercfg -h off

That last command alone can free up 4–8 GB instantly.

> Step 3) Check space again

Type

dir

to verify you're still on C: and to check it’s not showing errors.

Then type

notepad

In Notepad, go to File > Open, and under “This PC,” look at the C: drive, it should now show some free space.

> Step 4) Close everything and reboot the system

Type

exit

If all goes well, your PC should now get past the blue recovery screen.

Let me know how it goes. If it’s still stuck, we can force Windows into recovery and move files to another drive or repair the install. You’re very close now, we’ll get it working.
