Question Nightmare System drive expansion
Question Nightmare System drive expansion
Someone could assist by clarifying the reason behind your issue. The situation involves a Windows 11 24H2 system that was fully patched, but moved to a larger 1TB SSD after replacing a smaller 250GB M.2 drive. Backup with Acronis was successful, and the machine started normally. However, the recovery partition was located at the end of the drive, so it was restored as-is without expansion. Attempts to manually move or expand it using tools like Partition Wizard or AOMEI Partition Assistant failed to boot, resulting in a persistent "Inaccessible boot device" error. Despite troubleshooting and manual recovery steps, the system still wouldn’t start properly. I considered giving up but eventually decided to try a more hands-on approach. Eventually, after several attempts, I restored it again and managed to boot normally once more.
You're dealing with partition issues, and probably when you started this situation you forgot to add the hidden boot partition. Particularly if you mentioned partitions in Acronis but omitted all of them on the OS drive, there might be a connection. It could also relate to security keys—though that's less likely, though I've encountered it occasionally. Most often it happens after a BIOS update, but also when trying to recover an installation lacking the right credentials, which might have been stored on a partition not included in your backup process. At the very least, the EFI system partition, the main C: drive where Windows is installed, and the Recovery partition should have been present.
Without the EFI boot partition, recovery efforts will fail completely, especially if it wasn't part of your backup or image. My recommendation is to use another system to transfer essential files to an external location, perform a fresh installation, and then re-upload those critical files once more if needed. Frequent reports of "inaccessible boot device" usually stem from the Windows boot manager not being backed up or being stored on a different drive than the C: partition, which simply wasn't included in your backup routine.
Avoid actions like resetting, refreshing, or restoring. Instead, perform a clean installation. Do this once, and then ensure future Acronis backups contain every partition on the OS drive. Also, during a clean install, make sure no other drives are connected—only the installation drive (likely USB or optical) and the target drive should be attached, preventing the installer from mistakenly recognizing an old Windows boot manager on another partition and skipping creation of a new one.
Thank you for your reply, but I believe you overlooked an important detail. That is, once the drive was recovered, the system booted normally, which confirms that all key partitions were successfully restored. The issue only arose after moving the recovery partition and extending the C drive. As mentioned earlier, I verified this in the UEFI BIOS during the problem, and it confirmed that the Windows Boot Manager was correctly set to recognize the newly recovered drive.
I've repeated the same steps several times when changing my main laptop's storage from 125GB to 256GB, then 1TB and finally 2TB using Acronis for a full backup. After that, I restored the same data onto the new NVMe M.2 SSD that was installed instead of the older drive while booting from the Acronis rescue media (starting with ATI 2018/2019, then 2020 and 2021 versions using Bruno's MVP Assistant). Each attempt succeeded, including moving the Recovery partition with MiniTool Partition Wizard and adjusting partitions to fully utilize the extra space.
The laptop originally ran Windows 10 with UEFI/GPT, later upgraded to Windows 11 and is now on 24H2. I've documented this process in the Acronis forum thread about Steve migrating an NVMe SSD.
However, sharing my successful migrations doesn't solve your current problem. A helpful tip I've used when facing boot issues is to use Macrium Reflect boot media, which includes an option to Fix Windows Boot Problems in the Restore menu of the media.
For those without Macrium Reflect, booting from Hiren's BootCD PE offers a chance to launch an older version of Macrium Reflect 7, which provides the same fix option.
Additionally, I recommend taking a simpler approach: perform the initial restore to ensure a successful boot into Windows 11 on the larger SSD. Then move the Recovery partition and restart to verify if Windows 11 boots correctly. Proceed further by creating a new partition in the available space instead of expanding the OS C: partition, and test booting again.
Try to pinpoint exactly where the issue occurs during this process.
Yes, I followed the Minitool partition wizard as you advised, which surprised me since it didn’t work (sorry if your ears were irritated last night... lol, I wasn’t thrilled). The fact that it didn’t function, along with the other tools, made me suspect something else was involved. However, I didn’t try the move recovery and reboot. I did partially follow your instructions but ended up simplifying the process—recovering and then using MS disk management to expand, but that also failed. I’m not sure I attempted the move recovery step.
I’ve grown tired of this situation and thought a rebuild would be faster, especially since I’m just guessing and trying random fixes (and it’s still not working). Based on your experience, it should have worked. I’d appreciate any insights into why it didn’t.
The only additional detail I missed is that the 24H2 build is a bit damaged—meaning the PC isn’t genuinely Win 11 compatible (CPU not supported). There’s a workaround to bypass the check, but I doubt that’s the real issue.

Reminder - during the first boot after cloning, the old drive must remain physically connected.
This step is mandatory. Ignoring it may corrupt the cloned drive and require re-cloning.
Yoji, I attempted the Win 11 bypass method earlier just to understand what it entailed, possibly in a virtual environment, but haven't pursued it further. It seems like such an effort would be too complicated when Microsoft can easily alter the situation at any moment.
I didn’t expect the bypass to trigger the problem you’re experiencing, particularly since everything remained stable until after moving the recovery partition and resizing the partition.
I’ve been moving my older and some newer PCs to Linux instead of trying to circumvent Win 11 requirements, preferring to stick with the usual approach given Microsoft’s recent push for all new installs to require an MS account.
Sorry.. it was too late, I rebuilt the machine now. But it seemed identical to the original, except it had around 750Gb free space after the recovery partition. It wasn't a clone—it was a restore system image from a backup. So the steps were:
1. Backup the entire system drive with Acronis.
2. Create an Acronis recovery USB on the machine.
3. Remove the old SDD.
4. Install the new SSD.
5. Boot from the recovery media and restore the backup.
Just to confirm again, the recovery worked perfectly— the machine started up immediately after.
If by saying "you lose an element of your boot process" you mean "you lose your whole ability to boot," and "When you enlarge your partition" means "when you move the recovery partition to the end of the drive and extend the C drive space to use up the free space," then yes.
But I explained it in detail for clarity, but if you find my explanation helpful, please let me know.
