    Unable to restore Asus X550CA using Asus recovery DVDs


    Hello,
    I have in my possession an Asus X550CA laptop which was running Windows 8.1 before it failed to boot. The machine cycled through the automatic repair, failed, and then did nothing. The advanced bootup options were useless, including chkdsk, sfc and the usual suspects. The recovery partition was apparently missing, atleast, I couldn't use it, but doing a diskpart confirmed it was there so I suspect the 8.1 upgrade broke the link to it.

    I tried the "refresh your PC" option, but this told me the drive was locked, and disabling secure boot via the BIOS did nothing (thought it would at first). In addition, the reset your PC option wanted recovery media which I didn't have at the time.

    I ordered the official Asus recovery DVDs as the laptop did not have media created when it was new, hit F9 and went to the "reset your PC' option, but it told me the recovery media wasn't valid. Odd given it's official Asus media from Mentor Media, for that specific machine.

    From the legacy BIOS I booted from the DVD, it loaded the Asus specific Windows 8 recovery options from the disk and I get as far as "Start rebuild Windows system process", with "processing...." underneath and the machine does no more.

    I've also tried UEFI booting from the DVD drive and get the same as above.

    Any suggestions welcome please!

    Regards.

    Is the ASUS recovery media Windows 8.0 or 8.1? It may be because the recovery disks are 8.0 and it's a conflict because your now running 8.1. The 8.0 to 8.1 upgrade does break the factory recover feature on some laptops. ASUS for sure I think. I have a K75DE, that shipped with Windows 8.0. I clean installed with Windows 8.1 from here, Create installation media for Windows 8.1 - Windows Help. It reads and uses my 8.0 OEM embedded code and activates online automatically. no muss no fuss. That tool will create a bootable USB thumb drive that will work with UEFI for you. If you need any more info just ask and i'll see if I can help. I don't know why your getting the "Start rebuild Windows system process" message and the lock up? It may be because the partition structure has changed on the Drive. I created a Recovery drive, then swapped in an SSD and it would not work on the SSD. It kept saying required partition missing. That's why I bailed and did a clean install. I was leaning in that direction anyway.

    EDIT: If I don't get back to you tonight don't panic. I have company coming and may not get back online until tomorrow morning. Have to go now.

    can you boot into safe mode? you can boot into safe mode to restore your system. If you cannot boot into safe mode, I suggest you boot a bootable media with desktop created with another computer to restore system.
