Unfortunately after trying to flash my bios with your mod, I have been unable to boot and continue to see the boot manager not found error. There must be something that I missed even though I was sure to have followed all instructions correctly and checked the various prerequisites. I have read all over the net, through the appropriate readmes, but am still at a loss. I have also tried to access bios recovery but the use of fn+b does not work, the instructions given here have unfortunately not worked for me. My system is a P150EM Any advice would be much appreciated. p.s I have been able to boot into windows by changing the loading order and selecting my secondary hdd (no os installed) as my primary boot device replacing the ssd (os installed). I have no idea why that needed to be done.
