My laptop has 2 drives: SSD and HDD. Originally the SSD was 60gb. It was upgraded to 240gb. The HDD is 1000gb. Both drives have a Windows partition. I don't know why, since I inherited the laptop from another person. The SSD has Win10 pro, which was upgraded from Win10 Home. Over the weekend the PC stopped booting from the SSD.
In legacy BIOS mode it boots from neither drive. In UEFI BIOS mode it boots from the HDD but gives a limited version of Windows, with no start menu. Basic windows utilities can be run from the command prompt. I have Windows Explorer, Device Manager, and Computer Manager all running.
I notice the Drive C: and D: have been swapped; but Disk 0 and 1 remain as they were. The HDD is still Disk 1, but now labelled C: The SSD is Disk 0 and labelled D:
I ran a disk check on the SSD but found no errors. Windows Defender finds no virus. Computer Management, Disk Management report
Disk 0 :
100 MB, Healthy (EFI, System Partition) D:, NTFS, 220.87gb, Healthy, (Wim Boot, Primary Partition) 450 MB, Healthy (Recovery Partition) 11.35 GB, Healthy (Recovery Partition)
Disk 1 :
100 MB, Healthy (EFI, System Partition) C:, NTFS; 930.85gb, Healthy, (Boot, Page File, Crash Dump, Primary Partition) 450 MB, Healthy (Recovery Partition)
Those are my 7 Primary Partitions.
Q1: Why did Windows swap the boot drives around like that? Q2: Why will neither drive boot using Legacy BIOS? Q3: How can I fix it? Q4: Am I right in thinking that I need to make a recovery partition on a DVD, CD, or USB, and boot from that. Run Diskpart, and swap the bootable partitions over? Q5: I cannot make a recovery partition from this PC. Can I make a recovery partition from another (Win10 Home) PC instead?
PS1: The O/S on the SSD is Win10 Pro. PS2: I'm almost certain the "11.35 GB, Healthy (Recovery Partition)" will be Win10 Home (what it originally was) PS3: This laptop is an Acer Nitro VN7-591G
