Fail: Install Win7 from USB

Hey

First of all, i'm german, so please execuse me for my bad english.

Now, spot on the problem

This PC here:
Builder: Dell
Type: Optilex 755
CPU: P5
RAM: 1024 MB
HDD: 150 GB

i want to install Win7 Prof, cause there's only a CD ROM Drive, i have to boot it from USB.

The Win7 Installation Assistent popped up and all seems to work correctly.
NOWWWW !!!!

At the point where you can choose the Partition on which you want to install Win7, it fails.

"System partition could not be created or found"



Some Information to regard: In BIOS the hard disk is set on top of the boot priority




thanks taccu

Your post is very confusing.

If you want to boot from usb, usb should be at the top of the boot priority list in the bios.

Is there an option to boot from usb at all in your bios?

so sorry for my confusing post

my harddisk is set on top of the boot priority and usb as 2nd.

anyway it boots from usb.

so if i click on "Next" this error occurs "System partition could not be created or found"


Clear?

Check for newer BIOS version update, set SATA controller in BIOS setup to AHCI first, then IDE if necessary.

If update not available, then clear the CMOS: http://pcsupport.about.com/od/fixthe.../clearcmos.htm


Try wiping the HD, creating a partition, format and set to active. Boot installer, press Shift F10 at bootup or select Repair console to open Command Line, type:
DISKPART
LIST DISK
SELECT DISK 0 (or Win7 HD #)
CLEAN ALL
CREATE PARTITION PRIMARY
SELECT PARTITION 1
FORMAT
ACTIVE
EXIT

ok

i installed a dvd drive, took the original win7 dvd and the installation worked.

So something must be wrong with the usb stick.

Will make some tests.
