I am trying to downgrade my Aspire V3-551 to Windows 7 Professional. I has Windows 8 on but it runs very very slow plus it takes a long time to boot. I cannot get to boot from system cddrive a USB Floppy Drive or USB CDDrive. Only the HDD0 shows up in the boot menu on boot manger.
I have installed a new Hard drive it will show up in the Bios but not in boot manager.
Any Help.................Tx..Blackpete
