Yes, you can make USB boot drive. However main problem is the Smart... error. It is your hard drive. You need to fix that first! Try reseating the drive. Next go into BIOS by pressing F key during boot. Might be F2? Make sure BIOS recognizes the hard drive.

Once you get the drive going again, you can start the install / repair again. USB drive tool.

Causes of BOOTMGR ErrorsThere are a number of possible causes for BOOTMGR errors, including the most common "BOOTMGR is missing" error message.

The most common reasons for BOOTMGR errors include corrupt and misconfigured files, hard drive and operating system upgrade issues, corrupt hard drive sectors, an outdated BIOS, and damaged or loose IDE cables.

Another reason you might see BOOTMGR errors is if your PC is trying to boot from a hard drive or flash drive that is not properly configured to be booted from.

1. Restart the PC. The BOOTMGR error could be a fluke.
   
   
2. Perform a startup repair of Windows. This type of installation should replace any missing or corrupt files, including BOOTMGR. Continue troubleshooting if this does not resolve the issue.
   
   
3. Check your floppy and optical drives for media. Often times, the "BOOTMGR is Missing" error will appear if your PC is trying to boot to a non-bootable floppy disk or CD/DVD.
   
   Note: If you find that this is the cause of your issue and it's happening regularly, you might want to consider changing the boot order in BIOS so the hard drive is listed as the first boot device.
   
   
4. Check the hard drive and other drive settings in BIOS and ensure they are correct. The BIOS configuration tells the computer how to use a drive so incorrect settings can cause problems, including BOOTMGR errors.
   
   Note: There's usually an Auto setting in BIOS for hard disk and optical drive configurations which is usually a safe bet if you're not sure what to do.
   
   
5. Reseat all internal data and power cables. BOOTMGR error messages could be caused by loose or malfunctioning power or controller cables.
   
   Try replacing the PATA or SATA cable if you suspect it might be faulty.
   
   
6. Update your motherboard's BIOS. An outdated BIOS version can sometimes cause the "BOOTMGR is Missing" error.
   
   
7. Perform a clean installation of Windows. This type of installation will completely remove Windows from your PC and install it again from scratch. While this will almost certainly resolve any BOOTMGR errors, it's a time consuming process due to the fact that all of your data must be backed up and then later restored.
   
   If you can't gain access to your files to back them up, understand that you will lose them all if you continue with a clean installation of Windows.
   
   
8. Replace the hard drive and then perform a new installation of Windows. If all else has failed, including the clean installation from the last step, you're most likely facing a hardware issue with your hard drive.

BOOTMGR Errors Apply To BOOTMGR issues apply to Windows 7 and Windows Vista operating systems only. Windows XP does not utilize BOOTMGR. The equivalent function in Windows XP is NTLDR


Whish you the best luck.

Bootmgr is short form for Boot Manager and is the Windows Registry File that must be present to allow Windows to boot.
It is either corrupt or missing. In other words, you will not be able to boot without the use of your recovery disk, that you made when you first bought your laptop, or your Windows disk.
Insert either in your DVD drive and boot the laptop, you will be given the opportunity to recover your system or rebuild your system from there.
If you press F8 whilst and just before it boots, you may be lucky enough to catch the recovery disk on your hard drive partition.
Good luck and I hope it fixes your problem.

Boot Manager is missing If the boot partition no longer can be found, then Vista will display the following error: BOOTMGR is missing. Press Ctrl+Alt+Del to restart
The Windows Boot Configuration Data file is missing required information
More Info MS KB 919529 More Info MS KB 927391 Check points for fixing missing boot-manager: Check that your boot device is configured properly Boot into Windows Recovery Environment (WinRE) and perform a "Startup Repair". Boot Manager is compressed If by accident having compressed the entire boot partition, then Vista will display the following error: BOOTMGR is compressed. Press Ctrl+Alt+Del to restart OR maybe try this first. Check points for fixing compressed boot-manager: Boot into Windows Recovery Environment (WinRE) and perform a "Startup Repair". If the above doesn't solve the problem then boot into WinRE again, but when selecting the Vista-installation, then press "Load Drivers" (Instead of "Next") and use the mini Windows Explorer to right-click the boot-drive and deselect "Compress this Drive" and choose Apply to sub-folders and files. If that also fails then boot into WinRE again, and go to the "Command Prompt" and execute these commands: compact /U C:\bootmgr compact /U C:\ntldr If you for some strange reason have lost your Vista DVD, then you can also use a Windows 2000 / XP install CD and enter the recovery console instead and execute the following commands: attrib -c c:\bootmgr attrib -c c:\ntldr


Try start up in Safe Mode press F8. Choose Safe Mode, when at the choice window, to select either Safe Mode Desktop, OR System Restore, chooses system restore and choose a time before you had the "Problem" and follow instructions. This should get you back.

go to a torrent and upload and save the Windows XP program to your hard drive. Try to install it from your hard drive but use your own Serial Number

Since you didn't post the Windows version, I'll assume Vista
