    Help with EFI partition recovery


    I was using a disk clone program and for some reason it wiped out the EFI partition on both the source and the target, the machine cannot boot.

    I downloaded the ISO image, put it on a flash drive, configured BIOS to look at flash and it does not boot off of it.

    Any other ideas? I created a Macrium Reflect rescue disk (on a Windows 7 machine) and it does not boot off of it either. It says "Windows is loading files. . . " and then it hangs.

    The machine is MSI Titan GT80 SLI.

    Move EFI partition

    its to enable win 10 to update to its anniversary edition.. it cant do this due to lack of C drive space i have had a quick try with the trial version of easus.. it didnt seem to be able to do what i want..

    i am assuming i cant just delete the efi partition but maybe i could.. as yet i havnt even figured out how to get into the bios of the thing.. maybe that should be my next step.. *Smile Help with EFI partition recovery :)

    diskpart could probably do it but figuring out how (it aint that user friendly) might be difficult without step by step instructions..

    Blank EFI Partition

    I have an ASUS R558UR.

    I had windows 10 installed on my laptop and I decided to again have a clean install of windows 10. I booted from USB and cleaned windows partition i.e. C drive and also cleaned EFI partition. I reformatted Drive and it had also created EFI partition of 100
    MB. I installed windows on laptop and setted that up. After installing windows my laptop it started taking a long time to boot about 90 seconds but earlier it took only 7-10 seconds. After analysing everything I found that my EFI partition is blank.

    Please suggest me how to write back EFI partition so as to reduce boot times.

    Thanks in Advace.

    Help with HP System Recovery partition

    I will try and cut this short:

    So i have this HP pavilion DV5-1987 laptop, that came with windows vista home premium 32bit. A couple of months later i installed a 64bit version, and about a week ago i installed Windows 7 x64 RTM. Both installations was a fresh install on the C partition, leaving the recovery partition intact and alone.
    Now i have regrettet and want the original os to be reinstalled. But it doesnt work.
    The bios options does nothing, i press ESC to get to boot options, choose F11 for boot to recovery partition, and it goes straight to windows 7.
    i search the internet for options and try these suggestions:
    Mark drive D as active partition (the rec partition). it still boots to win 7.
    boot to super grub from a boot cd, and press "AUTO MAGIC BOOTER" (something like that). it then shows me two identical "vista boot loader" to choose from, and both goes into win 7, and a third (other OS) that gives me and error and returns to grub loader.

    there a several other suggestions but either they wont work in my scenario or are another iteration of what i have already tried.

    So uh... help? please? if you need anymore information please ask.
