Windows 10: locked myself out of my own laptop

    locked up laptop

    this started yesterday. i downloaded the ARK Dev Kit but when i tried to install i recieved this message, "the system admin has set policies to prevent this installation". i attempted some surface quick fixes. ie: turn off antivirus. did not help. eventually i ran this line into my run command prompt: "net user administrator /active:yes" in an attempt to make my user account the true admin. restarted my computer.

    the sign in screen loads. i enter pin/password and i recieve this error : "the User Profile Service service failed the sign-in. User profile can not be loaded."

    i've attempted to restore a previous backup, which failed.

    tried fixing start up problems via shift-power up-babys first computer menu. failed.

    tried using rufus to make a flash drive bootable x64 win10 from the ISO. wont do it. the BIOS says usb boot is enabled. shift-restart-> use device-> select usb fails stating boot manager isnt set to allow it. so i get into boot manager and theres three options, boot windows, and two others almost identically named but not showing me my actual usb device. (though i did try all three options)

    so i tried to reset the pc, remove all files and it errors out stating it cant do that and cancel is the only option

    idk what to do here anymore



    lenovo ideapad touch p400
    win8 at purchase, running win10 for awhile now


    in BIOS i disabled secure boot and switched to legacy with uefi support. now the boot manager found the usb. reinstalling win10, finally.


    did not instal win10. eight partitions. all said same error. GPT partition incompatible. tried to format. it just didnt do anything.

    returned to shift restart menu. use device. lenovo one key service. was able here to restore yo factory settings with win8.

    tried to reinstal windows10. boot error on second reboot. returned to BIOS. restores UEFI and Secure Boot. tried again to reinstal win10.

    on first restart black screen for two hours.

    restarted and returned to win8. win8 updates to instsl and restart. 167 of them. tried that. it almost finished but encountered a failure to instsl updates post 160. now ots been trying to revert to win8 pre updates for two more hours.

    it says dont turn it off. so im leaving it overnight.

    what fo i do here? im almost ready to rip out the hard drive to keep as an external and just get s new computer.
