Windows 7: Win7 setup boot error

Win7 setup boot error

Well, I had win7 and wanted to do a fresh install on my Asus NETbook. I used a USB installation (no DVD drive) and everything was going fine up to 30 something percent. When I looked it reported some error and reversed the installation. Since then, when I turn the computer on it loads into boot and gives two options: "win7" and "win setup". It reports an error if I click on win setup about missing a file on D drive, but it loads win7 option normally. So, I cannot use setup disc to repair it, obviously. Any suggestions? I thought about starting installation inside a running win, installing it into a separate partition, and formatting C afterwards. Help.

Back up your files, unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. If an EFI BIOS, enable Legacy BIOS or Compatibility Support Module, set DVD drive first to boot, HD second. Then set SATA controller to AHCI. Save changes and Exit.

Then boot into installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here.

At first installer screen Press Shift + F10 to open a Command Box, type:

SELECT DISK 0 (after confirming Windows 7 target HD #)
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt.You are creating the partition here for the purpose of marking it Active which overcomes certain install failures.

I wasn't clear enough. I can not use any boot options. My boot screen consists of these two options: "win7" (starts windows) and "win setup" (shows error). There is an additional option - "Memory Diagnostic Tool" (which show no errors) but that's it. No resets, no setting up from where to boot. Nothing. Just one screen. I would try installing it again, but I can't make it boot from USB because, well, there are no options. And fixing boot requires booting from a disk. -_- I don't care about the data on HDD but I don't know how to wipe it clean from within a running windows.

You're waiting too long to boot into the installer as what you describe means it has passed the chance and is now booting into the HD. You must trigger the USB flash stick to boot just as the first BIOS flash screen appears and before it proceeds to boot the HD.

This video shows you how: How to Boot A Computer from CD or DVD - YouTube
In your case you'll want to look for the boot option for the flash stick, usually by name.
You can press or tap the one-time BIOS boot menu key at boot, usually F8 on Asus.

If it doesn't appear or doesn't complete then you may need to rewrite a confirmed ISO to stick from Steps 1 and 2 of Clean Reinstall - Factory OEM Windows 7
