Lenovo K450e - reboots continously and can't access bio to access Windows repair disc RRS feed

  • Question

  • I have a Lenovo K450e desktop.  In the last 6 months, when I restarted, it would continuously reboot before starting windows.  In the beginning, it was doing it maybe 10-15 times then it would start fine and I could login in.  Then it began to to it for literally hours and eventually would start properly and I could login.  The last time, it won't start windows, just keeps rebooting.  The problem is, nothing shows up on the screen and I can't access anything to press F1 or F2 to enter BIOS mode.  Keyboard is USB and it never gets recognized before it rebooting.  Nothing ever shows up on the screen either, no Lenovo logo or Windows logo, just completely blank then reboots.

    Wondering if there is some other way to force access to the BIOS so I can have the system start from the DVD drive where I have a windows repaid disc.  

    Windows is installed on a SSD I believe so all my data is on a HD that I can remove and probably recover my data but I am hoping I don't have to scrap the computer.

  • Make some tools that can be used for troubleshooting and backing up important files.

    Test the hardware.

    Find 3 flash drives that you can format (> or = 8 GB).

    On a working computer create:

    a) a bootable Windows 10 iso:


    b) a bootable Ubuntu flash drive:


    c) the third flash drive can be used to move files from the  problematic computer to the working computer

    Once you have the tools then you will boot the computer to the flash drive using the applicable F key:


    Ubuntu can be used to backup important files an test the drive.

    The Windows 10 iso can be used for troubleshooting.

  • No, if a computer even can’t access to bios, you need to contact Lenovo Technical Support and have the system shipped to Repair Facility for BIOS Reflash. Or check if there is other hardware issue.
