Error starting from boot menu

[Petey]

Installed: Backup Suite Home 5.5.2.2, OS: Win 7 Pro SP1 64-bit.
Problem: when trying to restart the system using Hasleo boot menu entry, I get this error:
"Windows failed to start. A recent HW / SW change could be the case/reason"
"A required device isn't connected or can't be accessed"
"Status: 0xc000000f"

All system devices (SSD + 2 HDD) are connected and work; nevertheless, only the OS-SSD should be needed, I guess.

I have installed the Home version on 14. Dec 2025 and tested the boot menu + the rescue media, and both worked.
Neither the hardware nor the OS (Win 7...) have been changed, as far as I know.
The old OS backup software, that I want to replace with Hasleo, started up with no problem.

What can I do now?

Thanks.

I'm not quite sure what you mean. Are you referring to encountering this error when selecting to boot into Hasleo WinPE, or after choosing to restart the computer while already in WinPE? This is important because it determines whether the error is prompted by Windows or by WinPE.

You mentioned December 14, 2025, which is normal. However, V5.5.2.2 was released on December 5, 2025, so this issue should not be caused by software changes.

Furthermore, what operations did you perform using HBS or other software before this issue occurred?

The PC was running in normal Win mode, and I chose 'Shutdown / Restart'. When the boot menu showed up, I chose to boot into Hasleo WinPE. Then, immediately after pressing Enter, the error message occured.

B.t.w., should the boot menu entry be deleted and created new with every update of the backup software (same to rescue media)?

Thanks.

The boot entry you added will be automatically removed during software updates, so you will definitely need to recreate it. I suggest you remove and then re-add the boot entry to see if the issue persists.

Have a nice day!

Removing and adding the entry solved this issue.
However, as you wrote before, there have not been any updates to 5.5.2.2. In worst case, I would not have been able to restore the OS.
Any chance to compare the current boot config with an OS backup I created after installing Hasleo and check for differences?

The most likely cause of this issue is that the WinPE files installed by HBS have become corrupted or were abnormally deleted. We recommend that you not only add WinPE to the boot menu but also create a bootable USB recovery media.

You could take another backup of the current boot partition and then mount both partitions (the old one that didn't work and the one from the current backup) with HBS.

Then there's WizTree, a tool that is normally used to find big files on a partition. That tool offers to export a CSV file ("Export to .CSV") with all the files and their sizes and change dates.

With those 2 CSV files on hand, you can then compare those with a tool like WinMerge to find differences in the file structure.

It's maybe not the easiest way to find diffferences between 2 partitions, but I do this very often and it works for me. 

Keep in mind though, that this will only compare the file structure of the partitions. The differences could also be somewhere else like in the boot entry itself or corrupt boot sectors etc.
