    As far as I know, there is no other way unless you can make a bootable USB drive. Is your Bios set to boot off of the DVD drive as the 1st. boot option? You can use your Windows 7 install DVD and go to the recovery/repair options from there.

    That's the problem - when I select the cd drive - if I select in legacy mode - i get an error message, if i select uefi mode i get redirected to asus preload wizard - nothing windows comes up. I have found an iso image of windows 7 install disk that I'm currently downloading. I'm going to burn that using imgburn to a dvd and see if that works. If not I'm stumped and will have to contact Asus directly to find out what the problem is. I don't like not having a windows system repair disc that I can't access!

    For anyone else who has been unable to boot a Windows 7 repair disc on a UEFI system, please read this:
    "It seems that if you create a Recovery CD using a UEFI system, it can not be used to boot that system. If I replace the CD with a Win 7 x64 Install DVD, it boots fine in UEFI." I have found an iso of the Win 7 install disc here:
    Need Windows 7 Install Disc - Microsoft Community
    All forums that report this common issue (When I boot from the newly created cd, I get an error Non-System disk or disk error, replace and press any key) say there has been nothing from Microsoft to correct this, however, users have reported that they've been able to restore system images from the install disk.

    Try using the DVD instead, provided in step 6 of Troubleshooting Windows 7 Failure to Start
    which also includes everything that can be done to start unbootable Win7.

    All of those commands are automated in Startup Repair along with many other possibly-needed fixes so I'd start with that.

    I downloaded the Win 7 install disc yesterday and can confirm that if booted in UEFI mode I can access it and use it to either re-install windows or use the system repair tool.

    If nothing else, I've learnt to check that all discs that I burn are bootable before just putting them away and assuming that they'll work when I need them. Hope this helps alot of other people out there......

    I would but I don't understand HOW to do what you're asking! Your entry is not clear to me - please bear in mind that I am very new to all of this and I'm guessing you're a seasoned veteran.
    i would very much like to know what you are asking me to do but you will have to clarify further and explain the steps in the process.
    What I understood from your original entry is that I would have to know the drive in which the bootsect.exe file lives and yesterday I had no idea how to find that out - until I found the command prompts this morning:
    diskpart
    select disk 0
    list volume
    which tell me the drive letter of the cd/dvd drive (mine is H).
    After exiting diskpart I put H:
    cd boot
    dir
    and I saw the bootsect.exe file.
    I'm guessing now that your command gets entered here?
    I'm guessing that

    That's why I reassured you that all boot repair commands are automated in Startup Repair.

    The steps in Troubleshooting Windows 7 Failure to Start are also based on years of collecting and prioritizing the steps required to do everything possible to start unbootable Win7, based on helping with countless thousands of these cases here since before Win7 was even released.

    You can also decide to skip to the steps to rescue your files and either run Asus Recovery or get the superior Clean Reinstall - Factory OEM Windows 7 without the factory bloatware which is especially bad with Asus and throttles Win7 from its native perfect performance.
