Inaccessible boot device: T5810
Hi first time poster here.
I cloned my Windows 10 installation using AOMEI Backupper (the 'clone' option) onto a Samsung 980 1TB SSD and installed it in my Dell T5810.
It keeps reverting to the 'INACCESSIBLE BOOT DEVICE' blue screen error window. I've tried a few YT fixes, but to no avail.
One article I've come across suggests I have to firstly change my Windows 10 installation from MBR (Master Boot Record) to GPT (GUID Partition Table) (these are partition types) (this is a legacy from having had Windows 7 installed on my machine): https://faststorage.eu/how-to-clone-windows-10-from-sata-ssd-to-m-2-ssd-fix-inaccessible-boot-device/
The comments on this article suggest it is a well thought out and effective method.
Does this sound right? Does anyone have any other ideas?
The new Samsung SSD is recognised in both the BIOS settings and as a new disk in Explorer (I have both the HD and the SSD installed currently - I tried removing the HD to see if it would boot automatically off the SSD but it did not).
Any help greatly appreciated.
Thanks Gorilla Warfare - I gave that a go but still got the same error.
Everything I'm reading suggests I will have to re-partition my HD to GPT, then clone it to my SSD and then install the SSD (after, I think, changing the BIOS settings to UEFI).
To be certain I don't lose anything I'm planning on buying an identical SATA HD, and clone my existing HD to it so I retain a HD in the original, working, format.
Thanks for your help.
What was the original source of the clone (NVME, SAS,U.3, another SATA drive)? Also, was the source machine a different machine from the T5810?
Usually, if the answer is "YES" for either, the problem can sometimes be fixed by fully going into "safe" mode in Windows and restarting from there. This would normally restore the default SATA drivers for what machine you're installing on allowing it to boot.
