Installing windows 7 from a USB stick

Hi there, My laptop has a DVD drive and installed Windows 7 because of this, but my sisters laptop only have a CD rom drive, and because the install rom is DVD format, i have to find other ways to install it, i managed to get the install to boot off my USB stick, but when i get to the point of choosing a partition it fails it says 'setup was unable to create new system partition'.

Now i have google'd this problem and people seem to be getting round it by removing there usb connections, but of course i cant otherwise install cant do anything, i tryed using a different program to re format the hard drive but still nothing, and i have noticed people havent had a problem with installing from usb.

Can anyone help??

Thanks Wizkid005

There are other methods to get a bootable USB flash key installer that might work for you.

Besides the one Corrine posted above, here is a MS tool for writing the ISO to stick: Windows 7 USB/DVD Download Tool

Then there is the Win2Flash method which works for some:

What worked for my Kingston Data Traveler is formatting it Primary FAT32 in Disk Mgmt., then copying the DVD's files over exactly as they appear when you Open DVD. It boots from BIOS under HD's in boot order listings..

If none of these 4 methods work, try copying the DVD files over network to your sister's netbook, then run Setup from desktop to overwrite the current OS.

Then you could use Vlite to split the ISO into multiple parts to fit on CD's.

There is a tutorial on how to use Vlite here: Bootable ISO - Create from Installation Files

It is fully automated: just load the files from DVD into Vlite, let it recompile ISO, then on ISO page use Split ISO Image wizard at bottom right.

It will be set by default to 700mb, which is size of CD and split the ISO into parts to burn separately.

Did you look over your BIOS settings carefully to make sure USB flash drive is selected 1st boot device. It's usually listed under Hard Drives.

Try clearing the BIOS CMOS:

Did you look for all related USB settings to make sure they are enabled in BIOS?

What is the SATA controller setting: AHCI, IDE or RAID? Try the first two in that order.

Use Win7 own formatting. Boot into Win7 DVD, choose Repair on second screen, click through to Recovery Tools list and open a command line, type:

SELECT DISK # (for Windows 7 disk)
clean all
create partition primary
select partition 1
assign letter=c:

CLEAN ALL is zeroing the drive which takes a long time. You want the deepest possible clean.

If you cannot wait then use CLEAN without ALL.
