Windows 7: Get invalid partition table while trying to install win from usb

Get invalid partition table while trying to install win from usb

Hi all,

I've tried several ways to format and copy my win 7 installation into the USB. I've also tried this tutorial and this tutorial, but it always says invalid partition table while booting.

I've putted the USB-HDD first in the priority on the bios boot priority.

Could it be my USB(Kingston 8GB)? Or is there another think I can try?

Thanks.

Are you trying to install 7 from a USB thumb drive, the install files are on the USB thumb drive?

Or are you trying to install 7 TO a USB drive?

No version of Windows will install or run from a Removable drive.

From USB...
I format the usb to fat32 and copy the files.

And in the tutorial it clearly said that I can install from a usb stick

So you are installing FROM a USB stick, not TO a USB stick.

Use the Microsoft Windows 7 USB DVD Download Tool. It is a program specifically to load the Win 7 install files from a Win 7 ISO on to a USB stick or to a DVD.

Well there lies the problem. But I seriously doubt your motherboard only sees USB sticks formatted FAT32 and not NTFS. The format should not matter one bit.

When I format it to NFTS / uses the win 7 tool (which format to ntfs) - the starting process doesnt stop at the usb, it doesnt says invalid partition table - it just continue to the windows (even due the hard disk not on the boot priority sequence)..

If you boot from usb it reads its MBR. MBR reads active partition and executes its bootsector.
MB
FAT32, NTFS, EXT2, EXT3, .... all supported if supported by bootsector. MB doesn't even know what fat32 and ntfs is!
I Can boot to linux from usb without issues.

What happens if you format as ntfs and try to boot from it?
