Windows 7: Can I start a computer without harddisk only by DVD/USB flash?

Can I start a computer without harddisk only by DVD/USB flash?

Assume I remove a hard disk from computer/notebook and put in a bootable DVD (with WinPE or Ubuntu) into DVD drive (or USB flash drive into USB flash port).

Can I start the whole computer in this scenario?

Or is a working hard disk required even if I boot the (Win 7 /Ubuntu) OS from DVD/USB flash?

Yes, you can remove the hard drive and boot into a bootable DVD or USB. No problem.

Can you actually run windows 7 from a USB drive? if so, how? Wouldn't you need a big usb flash drive?

I know you can run most Ubuntu flavors from a usb drive or dvd drive.

One issue I did come across, is some flavors didn't write correctly to usb drive using Win32DiskImager-0.9.5-install from windows 7. So, I used rufus-2.2 from windows 7 for those that didn't work and so far rufus seems to work for most distros (Not all distros have been tested by me though)

You can do most of them with Rufus. But, I don't know why you would want to run an OS from a Flash drive. It would be terribly slow and you will have problems with retaining what you install. The Live USBs are nice for a test drive or to use them for a specific purpose. But, using them for an every day OS, will be an unnecessary pain and terribly slow.
