Windows 7: Cant boot from a USB even though it's in device manager

Thanks for all the replies gents but it looks like a lost cause. Maybe MS have made it impossible but it's odd that they didnt then remove the Bios 'Legacy USB support' option unless it means something different altogether.

Take the point about security. It's a good one and easily overlooked but for me this is temporary. I just want to know what's on the disk before I clone it to the SSD which is playing up (crashes almost constantly). Being able to pop between the two makes comparison a lot easier.

The boot order is not related in any way to the Windows 7 OS Installation. It is a function of the system hardware controls and I have not seen a BIOS that does not have a way to access this option.

This is an explanatory web page from Samsung

Yes I've done all that without result. One thing that may be a clue is the USB option shown in the BIOS has 'N/A' beside it. But never any numbers

That would suggest to me that the USB HDD is not a bootable disk

I would expect that, if the disk contains a live installed copy of Windows, one that is prohibited to run under windows rules as mentioned above.

Alternatively ...
If the HDD contains an installer for windows this this may not be correctly installed on the HDD, (a HDD is basically considered to be a large capacity USB stick), special software is required to correctly write a workable bootable installer onto a USB device

I personally use Rufus to prepare USB devices for bootable use Full instructions are included in the link

Cheers for that. I looked at Rufus but it looked to me that I have to format the disk first. Is that correct or can it be made bootable without overwriting the W7?

Re reading your previous reply, are you stating that you cannot read the contents of the disk?, even though the disk shows in the disk management in Windows?

If this is the case then there are a few things you can try

No I can see all the folders and files when it's in the USB port.

OK if you can read the disk then it is working as designed, the disk cannot be booted into the OS on the disk due to restrictions in place.

You may have one option which is beyond my experience but it may be possible.

Windows 7 Installation - Transfer to a New Computer - Windows 7 Help Forums

You may need to install the old drive into the case, Not an option on a laptop or use an Esata connection to enable the work required there are USB-eSATA convertors available but not sure if these will get around the Restrictions or not

There is also a possibility to convert the existing HDD installation into a virtual machine which should be in the tutorials here but that is beyond my knowledge also
