Dual-Boot Vista/Win10 messed up by Win10 update RRS feed

  • General discussion

  • Hi everyone,

     - Start with Vista 64-bit SP2 on PC with two drives - OS on Disk0 - working fine for years

     - Downloaded Win10 64-bit English-International ISO image from MS on 23 March

     - Installed on Disk1 as Home edition on 24 March

    All works fine with dual boot Vista/Win10

     - Win10 Update arrived on 25 March (I think Win10 Cumulative Upate, but can't be sure)

     - Update installed with Shut Down on 25 March

    Now fails at dual-boot time:

      PC/Device needs to be repaired

      Required device isn't connected or can't be accessed

      Error code:  0xc000000e

    Fortunately F9 boots Vista correctly.  I conclude that either the dual-boot is messed up OR it recognises that the Win10 OS is messed up.

    I'm a hesitant to go further without expert advice as I'd hate to mess up the Vista possibilty ! ! !

    Many thanks for any help - David

  • I should add that all partitions on both disks are accessible from the Vista boot.

  • Further update - EasyBCD gives the following:

    Does that mean that only Windows10 needs repairing?

    Will this leave the dual boot intact?

    Switched on USB connected scanner & printer - boots OK

    Switched off USB scanner & printer - restarts OK

    Restart again - FAILS !

    F9 Boot into Vista (OK)

    Restart again - FAILS !

    F9 Boot into Vista (OK)

    Switched on USB connected scanner & printer - restarts OK

    As they say around here: WTF ? ! ? !

  • I may have a solution prompted by the above.

    I was surprised to see that he dual boot is controlled by DRIVE LETTER as seen by the Vista environment.  (What I'd seen in the past was by physical address e.g. dual Win/Linux).  I'd allowed the new partition for Win10 to take its default letter J: - which was alphabetically AFTER the letters assigned to the built-in USB card reader.  I guess that means that the existance of J: depends on the satuts of the USB - yes?

    Action taken has been to change the drive letter in Vista to be before the USB drives (miraculously the Boot Loader entry gets updated) and first boot, with USB scanner & printer off, has worked correctly.

  • Well that didn't do any good.  So I conclude that


    looking to see if I have any disk problems.
