    No F8 boot menu and "Windows 8 cannot verify the digital signature for winload.exe"

    Trying to test win 8 enterprise on a dual boot system with win 7.

    Win 7 is on OCZ revodrive PCI SSD, win8 is on a HDD. I get the above error while booting to win8. I can not get to the F8 boot menu to select booting without signatures. win8 boot/install disc repair option does not have 'advanced options' to reboot to safemode boot menu.

    Suggestions?

    Thanks

    Did you manage to complete the win8 installation, or is this a reboot as part of installation process?

    You could boot up the install disc - go to Repair my computer , then command prompt ( under advanced options) use note pad or diskpart to find what the win8 install partition drive letter is.

    Also find the active partition drive letter.

    Active partition might be the 100mb one because you had win7 first - if so , give it a drive letter using diskpart.

    Then type:

    bcdboot win8letter:\windows /s activepartletter:

    My drive set up is actually a bit more complicated. I'm not sure which active partition to use from which drive. I have several OS's I boot too. all work but win8. I do not want to kill the others just to make win8 work. see below for my set up from Acronis Disk Director.

    I think bcdboot win8letter:\windows /s activepartletter:
    should be
    bcdboot G:\windows /s C: ????
    or c: might need to be k:? k: has a file called bootsect.bak dated yesterday about the time I installed win8, long with files bootmgr, & bootnxt.
    what do you think??
    Thanks again for you help
