I installed Windows 8.1, on a GPT disk in UEFI mode (so three partitions in total, with 160 GB unpartitioned at the end).
I then installed Windows 7 SP1 on the empty space after the 8.1 partition.
All has been working fine and i was (able to dual boot into each OS using iReboot) [Note that the Windows Boot Manager menu was the black and white, not blue one if it makes a difference?]
I later used EaseUS Partition Master *on a different drive* but in same machine to change the size of a partition. For some reason this seems to have broken my dual boot. When I say broken, i mean Windows 8.1 is fine, but when try to boot into the Windows 7 OS, i get a black screen, for every.
I have used EasyBCD to delete the dual-boot BCD and re-create it, but to no avail.
Can anyone hazard a guess as to what the problem is and how i can restore my dual-boot setup?
I am running an intel z77 chipset with core i5 (i.e. recent machine). Secure Boot is switch off [because it is a really sh1t idea, introduced due to Microsoft to kerb the take up of non-Windows OS]. The disk is a Crucial M4 256 GB, it is completely error free and no other issues other than the above.
PS: A warning to others: UEFI is VERY flaky with Windows I feel, both in my testing at home and work. For resilience definitely go with MBR, the benefits UEFI bring do not outweigh the negatives).
