unetbootin - ntldr is missing

linux-howto

http://www.linuxquestions.org – I downloaded an iso for BackTrack4, and then used unetbootin to put it on an external hard drive. I restarted my computer, and selected the USB drive from the boot menu, but I get a black screen and then "NTLDR is missing...press ctrl+alt+delete to restart". Am I missing something simple? Would it matter if there were other items on the drive? I only have ubuntu 10.10 installed, but I recently changed from windows 7 and reformatted the drive. Any ideas or suggestions would be great. On the external drive i have an image of the old windows 7 drive. (HowTos)

Stories similar to unetbootin - ntldr is missing

After some consideration, I decided to install Backtrack 5 R3 on my spare hard drive. I was able to boot via the live dvd, enter bt5, and install bt5 on my external hard drive(was a full format then clean install). After restarting, I changed my bios settings to read the external hard drive first, it went through the HP splash screen and then hung on a black screen.

I installed the 12.04 iso with unetbootin to a flash drive then booted into the liveusb and installed onto an external hard disks. works flawlessly so far.

My question is; Am I able to boot to it from any other computer and use as usual without problems? Or will there be missing drivers and/or any other problems?

Thanks in advance.

Hi guys,

So I was looking into how to install Windows 7 from an external USB hard drive. I found a few different programs that allow you to do this by extracting the Windows 7 image file to the external hard drive in such a way that when you boot the computer up, it will boot from the external hard drive and bring you to the Windows 7 installation process.

I just installed ubuntu onto a blank hard drive with a 10GB partition and it went fine. When I restarted the PC (when it asked), I quickly changed the BIOS so that it booted from the HDD not the disk anymore. However now all I get is a black screen with

BOOTMGR is missing Press Ctrl+Alt+Del to restart

Not sure how to fix this issue?

[ubuntu] Boot Order Change 3 years 29 weeks ago

Hey, everyone!

My problem isn't actually in Linux, but most people here seem to be pretty knowledgeable about computers as well, so I figured I'd ask.

This was an official 64-bit download from the Ubuntu site, so it's kind of sad to see even that's not working.

I made a bootable Ubuntu 12.10 USB stick with USB Image Writer (mintstick) on Linux Mint 14 Cinnamon and then shut down after ejecting the drive.

Unetbootin can't see usb drive 36 weeks 4 days ago

I am trying to make a usb backtrack but run into problems cause when I start unetbootin I can not see the USB drive.

I have made sure the drive was mounted. I also tried unmounted. I did a reformat of the usb stick, fat32. Did not help either.

From within puppy linux I can see the usb drive and I see that the drive is empty.

I'm new to linux and am interested in learning it so I installed ubuntu 12.10 yesterday. Installation went smoothly and I chose "install alongside windows" option and I set about 50 gb using that slider and I thought I used 50 gb from c: drive but to my shock it used 50 gb space from f: drive.
