I just upgraded from Windows 8.1 to Windows 10 successfully.
I think I made a mistake of formatting the old Window 8.1 recovery partition (which was not needed anymore). This was done via the Disk Management utility in Windows 10. After that, I am unable to boot at all.
I ran the Window 10 USB Recovery utility and have tried using DiskPart, BootRec and BCDEdit utilities as described on various google posts. But nothing has helped.
Here is the current output from DiskPart:
List Disk Disk ### Status Size Free Dyn Gpt Disk 0 Online 465 GB 1513 MB * Disk 1 Online 3935 MB 0 B List Partition Partition ### Type Size Offset Partition 1 System 223 GB 1512 MB Partition 2 Primary 240 GB 225 GB List Volume Volume ### Ltr Label Fs Type Size Status Info Volume 0 D DVD-ROM 0 B No Media Volume 1 E Data NTFS Partition 240GB Healthy Volume 2 C OS NTFS Partition 223GB Healthy Hidden Volume 3 F RECOVERY FAT32 Removable 3935MB Healthy
BootRec /ScanOs does not find any Windows Installations. And I can't set a partition 1 active on DiskPart as I get the following error:
The selected partition is not a fixed MBR disk.
Startup and Recover options do not work. The BIOS is a UEFI Bios and I tried setting Legacy boot options as well.
I don't won't to lose my Windows 10 installation (which there but just not booting). Any ideas on how to resolve this?
