I have a Acer Aspire M5 laptop, it had a 500Gb hard drive and a built in 20Gb SSD running the latest updated 8.1. I replaced the HD with a 500Gb Samsung SSD, making an image of the HD and copying it to the SSD. Should be simple but in the process I formatted the 20Gb SSD - Stupid! Well it gives Boot manager not found, no bootable media messages, the recovery drive is not found nor is the winre.wim file, I guess they all lived on the old SSD. So I was stuck with a system that would not boot. I left it for a few hours and went out for a meal, turned it on again planning to play with the bios to try to get it to boot but it started, slowly but it booted up OK. Oddly and I cannot see why, if I do a restart it locks out and will not boot. Full power down and it locks out and will not boot BUT Full power down and leave it for a few hours, at least three then it will very slowly boot! Sounds stupid to me but I have played with it for days now! How does it boot at all? boot.wim is not on the system anywhere? Swopping the drives back doesn't change anything, clearly bits of the OP were on the old SSD! I have downloaded the 8.1 core ISO, X64 for the system but I'm not sure if it will work over the remains of what appears to be a phantom 8.1 installation. I have a full backup of the old HD and OEM key recovered from the system but the time delay bit freaks me out! Any ideas or suggestions would be welcome!
