Thinkpads Forum

Hi All,
I have X200 with XP on it. Created bootable USB with Windows 7 on it set boot order form usb and gives me " Error loading operating system".
I googled alot and could not find any solution for this.
Also I put this usb flash on my work T410 and it comes up and starts loading Windows 7 fine.
So i do not understand the issue here.
Any help is appreciated.

Here are some specs on it
- P8600 processor.
- Bios version is 3.20.
- 3GB ram.

Hi there

Not sure if your "x200" is a tablet . if so ; than there is reason WHY... eg the "boot.bak" etc files = very different from normal laptops eg t410.... so in short , I would 'create' a tablet boot USB.
Or there is something wrong with your boot sequence - reset that in Bios ...

I have had my X220T (outdoors version) boot from USB(32gb) + mSata +SSD+external Drive(either from the dvd or hardrive) ,,,,, all of them works very nicely!...(knows yours is x200)

Hope this helps

did you check your usb-Win7 disk on other pc or laptop
did you follow this procedure: link
in my opinion the best solution is just burn iso to usb using ultraiso > tutorial
did it few times and never had any issues

Thanks for the reply.
My x200 is not a tablet and i did burn the windows 7 iso onto usb and made it bootable.
I tried that usb on my work T410 thinkpad and it worked.
Also i pressed f12 and selected to boot from usb so even if boot order is not correct which wasnt the case here it should still be ok right?

Anyone with x200 done upgrade to windows 7 with usb?
I really need help all.

Hi there
Not sure if X200 laptop has cability of USB boot - even if it shows in BIOS as an option - it might not be capable of that - since Lenovo has kinda consolidated few Bios that are now in common to lots of TPs. I know for SURE that X201, X220 series (laptops and tablets) do Did boot from my 64Gb usb stick.(sorry I never had one of x200 tps)I would call Lenovo tech Support and ask for levelII Bios boot versification via USB

Here is a link from a fellow Aussie - for USB boot- (maybe try this options etc ,,, not sure why but it took me couple of different things b 4 my USB boot worked - but that way at first fews weeks after Win7 release etc ,,,)

Hope this helps

ok I figured it out FINALLY!!!!
I was using LEXAR brand USB before so decided to change the USB and tried SANDISK
and it worked suprisingly.
I have NO idea how this works now.
So to anyone having 'Error Loading Operating system', try changing USB brand and see if it works.
Windows 7 is installed now whewwww

The last comment from gassian totaly worked for me and it saved me [censored] load of time. tx man

Once again-good idea,try it!

I had a similar problem on Thinkpad X200 when a usb was made with MS tool. It did not boot, just showing a flashing cursor. The problem was that MS tool makes NTFS-Win7 bootable usb and not all BIOSes recognize NTFS. When usb was made "manually" with step-by-step preparation of FAT32-formatted bootable drive, then unpacked Win7.iso file there (instructions found on the internet), it finally booted and quickly installed Win 7 on HDD smoothly. This USB was made using different Win 7 laptop, because X200 had a wiped-out HDD (however NTFS-formatted - with Parted Magic).
