I was wondering whether you could help, basically I have a 4TB SSHD installed which I have formatted as GPT and have allocated the following Windows OSs to the following partitions in ascending order: Windows Vista Ultimate SP1 x64 (Partition 3), Windows 7 Ultimate x64 (Partition 4), Windows 7 Professional SP1 x64 (Partition 5), Windows 8 Pro x64 (Partition 6), Windows 8.1 Pro x64 (Partition 7) and Windows 10 Pro x64 (Partition 8). When installing Vista using the partition wizard, I created each partition with 120GB of space apart from Partition 8 which I allocated 1.5TB, Partition 1 (System Reserved) and Partition 2 (ESR) were automatically created when creating a partition for Vista, the remainder of disk space I have left as unallocated for the future just in case I want to create new or expand existing partitions. However the problem I have got when booting into Vista, it comes up with a BSOD error code *** STOP: 0x0000001E (0xFFFFFFFFC0000005,0xFFFFF80003ACC7,0x0000000000000000,0xFFFFFFFFFFFFFFFF) that I cannot fix even after reinstalling the OS which was now changed the bootloader from Windows 10 to Windows Vista but Windows 10 is the default OS that the PC boots to. Is there anyway to rectify this issue? Your help would be much appreciated.
