Lost boot menu


New Member
I have a problem with my PC boot process, I have a dual boot system with Win7 and Linux mint each on it's own HDD. I have just replaced my motherboard which is a used one that came with no driver/ installation disk. Having got it working ok I was setting up the boot sequence using Easybcd. Whilst twiddling with the boot sequence I deleted the easybcd choice of Win 7, now I cannot get it to boot at all. I get the windows boot manager screen which shows only one entry "Neogrub bootloader and nothing else.
I have tried booting into Safe mode (F8) but nothing happens. I then try to repair via my installation disk but the first screen appears but I have no mouse pointer or keyboard function so I cannot select from the installation menu. I'm now stuck for answers, can anyone help?
