The harddisk in my Lenovo B575e has crashed. Windows 8.1 won't start. And I tried repairing the OS but it fails. I hooked up the hdd to another computer via usb and ran a scan. It is stuck. It sounds like it is trying to read but cant get any further. The scanning also gets stuck. File explorer does show up when connecting the hdd via usb and I can read files. So perhaps there are som bad sectors that holds windows files needed to start up.
My first attempt to make this computer useful again was to try to install windows 7. As I have the cds. I found out that I can't access the bios. All keys are tried. I get into a menu instead that gives me the options to repair OS, restart and selecting a device to use. As mentioned reapaing failed. I selected ATAPI CD. The CD drive spins up and a message shows up: Secure boot. secure boot: Image failed to verify with access denied.
I removed the harddisk and a boot menu appears. I selected cd rom drive. but it just blinks when hitting enter.
I pulled out the little CR32 battery inside and disconnected power cord and laptop battery. I forgot to put in the small battery again when turning it on but the boot menu still appears. How can a bios function without the battery.
What would you do to get this computer up and running again?
