My computer has 3 disks:
- 1 SATA SSD 256GB, one partition: Windows 7 (C:)
- 1 SATA SSD 256GB, one partition: Data (F:)
- 1 SATA HDD 750GB, three partitions: Data (E:, G:, L:)
The mechanical disk (HDD 750GB) is faulty and I can merely list its directories. But if I remove it Windows doesn't start anymore and BIOS/UEFI asks for a valid boot media.
Using the disk manager of Windows 7 I discovered that it has a 100 MB partition at the beginning, without any letter assigned, with this description: "system, active, primary partition).
Instead, the C: drive has: "boot, paging file, primary partition". I also add Windows now take about 15-20 minutes to boot and to shutdown, I bet due to the required access to the faulty disk.
I've already recovered important files on the HDD, but I'm not sure what I have to do to keep Windows booting even disconnecting it.
