I have Windows XP but I want to upgrade to Windows 7. Since I have no DVD-ROM drive (only CD-ROM)
I used WinToFlash (v0.4.0021 beta) to create bootable flash drive with Windows 7. After Windows Setup Transfer Wizard completed I restarted the computer and then booted from USB drive.
And I get this message: "NTLDR is missing". I turned on Windows XP and searched the original disk of Windows 7 and the NTLDR wasnt there.
The disk is brand new and I have tested it on Virtual PC. No problems while installing it on the Virtual machine.
I used Kingston 8 GB flash drive.
Please Help!

  1. Boot from the flash disk with Windows 7.
  2. Open the command prompt
  3. Change to the C: drive

  4. Type the following:

    bootrec /fixmbr

  5. Then:

    bootrec /rebuildbcb

  6. Exit and restart your computer.

If this does not work for you then, follow same procedures but now type:

bootrec /fixboot.

Use the Windows 7 USB/DVD download tool instead.

If you run into issues, follow the guide Installing Windows 7 on a netbook.
