General :: Removing Grub From MBR Of Flash Drive
Nov 29, 2009
I have a flash drive that I used on my old netbook to temporally hold a copy of ubuntu as the netbooks internal drive was dead. I have since got a new netbook and wanted to return the flash drive to simple removable storage. I've re-partitioned it back to 14gb fat32 2gb ext2 and everything is working fine. Except that if I try to boot with the key inserted grub loads then errors imminently (sort of obvious if grub is still in the MBR but there is no menu.lst file anymore...) Googling for removal of GRUB just gives me loads of hits for how to restore windows mbrs when you dont want to keep linux anymore. None of these methods seem to have any targeting. I need to remove grub from sdb while keeping it intact in sda. sdb shouldn't even be bootable, so that when boot from usb is higher in the bios than boot from hdd the usb key is ignored and the hdd is booted as normal.

I took some videos off a usb flash drive, then went and selected " safely remove usb" and the light continued to blink on the flashdrive, I pulled it out any way, and the root folder turned red... everything seems ok, but how do you know when it's ok to safely remove a usb devise ?

The search function does not like "U3" so I cannot locate the latest in removing it. Has anyone figured out how to do so using Linux? (Explosive, maybe, but was the Stupix worm hidden in flash drives using the U3 tools?)

I tried to install Ubuntu on an external drive, but it doesn't boot, but it installed GRUB on my main HD, and now I can't even boot Windows. I only get a "grub rescue" prompt. I need to remove GRUB. How to do it?

First time poster and recent Ubuntu adopter. I recently installed 10.10 on my main HD alongside a separate windows (xp) partition (it worked perfectly). Then I decided to get fancy and installed 10.10 to a flash drive directly from a live cd. I attempted to boot from the flash drive, and got a black screen with a blinking underscore for about 10 minutes, then I forcefully rebooted. Now, whenever I attempt to boot at all from my main HD I get "error: no such device and a ton of misc numbers. And the flash drive will not allow me to boot from it. Currently, I'm working within the Live CD.
I have a few projects I need to complete with Dreamweaver inside XP, so recovering it completely would be nice.
Code:
Boot Info Script 0.55 dated February 15th, 2010
============================= Boot Info Summary: ==============================
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #1 for (,msdos1)/boot/grub.
=> No boot loader is installed in the MBR of /dev/sdf

I have an issue after the installation of debian 8.2 on an usb flash drive:
I had debian 8.2 and windows 8.1 running on a single SSD. Everything was fine. I wanted to install a second debian on a 32gb USB flash drive as a live system. After the installation I am not able to boot my debian (SSD) without the flash drive plugged in. I only get a grub rescue prompt. Booting windows still works. It is also possible to boot both debian systems if the USB drive is plugged in.
So it seems to me, that the debian bootloader was accidently installed to the USB flash drive and the original bootloader on the SSD does not work properly anymore. I used a netinst image from a second USB flash drive to install debian to the first USB flash drive.
Update fdisk output:
/dev/sda1 2048 2050047 2048000 1000M Windows recovery environment
/dev/sda2 2050048 2582527 532480 260M EFI System
/dev/sda3 2582528 4630527 2048000 1000M Lenovo boot partition
/dev/sda4 4630528 4892671 262144 128M Microsoft reserved
/dev/sda5 4892672 223840255 218947584 104,4G Microsoft basic data

I wish to create a bootable disk for my existing grub legacy. I do not have a floppy drive. Could this be done on a CD-RW or flash drive?

essentially what the title says. Clonezilla cannot be installed in ubuntu so running a live linux on the usb and installing the applications in that is not an option.

I'm trying to uninstall backtrack 4 and put windows xp on my hard drive. I bought the hard drive clean and immediately put backtrack on it I've never dual booted with windows. I kept getting the no-apic timer error when I stuck in my windows xp boot disk and booted from the CD. I then used my live backtrack 4 disk and deleted the partition so I have a blank hard drive (so I thought). I tried booting from the windows recovery disk and I kept getting the GRUB error 22.
I went back onto the backtrack 4 live cd and created a partition on my hard drive, tried to boot to the windows recovery disk yet again and now I'm getting the GRUB error 15. I've been at this for about 2 hours now and haven't found an answer anywhere. I've tried going sudo grub then doing find/boot/grub/stage1 and I get the error 15 in there as well. All I want to do is install windows. All solutions I've seen say to do fixmbr in windows command line but the only disk I can boot to is backtrack 4 so that's not an option.

Server (LVM):
500GB
320GB
I want to install a new 500GB and remove the 320GB, of course moving the data on the 320GB to the new 500GB. I have an external 1TB in enclosure that I can plug in to move the data over, but how do I move only the data on the 320GB to it?? I found this [URL]. But that is only to move the data to a new replacement disk, but my external is only temporary to move the data from the 320GB until I remove it+install 500GB, then move the data back. Not enough space on the 500GB already on server to move everything from 320GB to it, just in case that seemed the obvious thing to do.

I'm looking for a way to quickly remove all data/partitions/boot records from my hard drives while running linux (distribution is irelevant). There are lots of ways to do this that I know of, but they all have some problems. Here's a list of what I've tried/thought of already. The most obvious is fdisk: Simply delete all the partitions. This usually works just fine and is very quick, but there are times it just doesn't....I'm realy not sure what gets left behind...I remove the MBR as well..but whatever it is, it's in the way. A couple other options are:
dd if=/dev/zero of=/dev/sdb bs=1M
shred -vfz -n 1 /dev/sdb
Both of these approaches are great if you're selling the components and want to make it very difficult for anyone to recover data. The draw-back is they take so very long to run. I've got four 1.5 TB drives that I've been writing zeros to for 2 days now. If you thought watching grass grow or paint drying was boring. A hundred years ago or so, when I was doing tech support for Windows 95 users we used this nifty dos-based debug script to wipe the hard drive. It was sort-of a last resort thing, but it worked beautifully, most of the time. If the customer had already formated, fdisked, fdisk /mbr, reinstalled Windows, but still couldn't get the thing to work, this would clean the drive so you could do a fresh install.
Just in case someone wants this, I'll post it. To use: first boot to some type of DOS environment in which you have the program "debug".
debug
-F 200 L1000 0
-A CS:100
xxxx:0100 MOV AX,301
xxxx:0103 MOV BX,200
xxxx:0106 MOV CX,1
xxxx:0109 MOV DX,80
NOTE: Type 80 for the primary hard drive - HD 0,
or type 81 for the secondary hard drive - HD 1.
In most cases, the primary hard drive is required 80.
xxxx:010C INT 13
xxxx:010E INT 20
xxxx:0110 (Leave this line blank. Press the <Enter> key to continue.)
-G
The message Program terminated normally appears. How to do something like that while running linux?

I made a persistent install of Ubuntu on a flash drive. I made changes to that installation. The software (Unetboontin) sets this all up. I think it partitions it for you. How do I image that flash drive to another flash drive?

I have been playing around with a Ubunto 10.04 live cd (32bit) on my mac. I want to be able to boot this OS (or similar) on my Mac, and on any other computer (PC or Mac). I also want it to remember changes and files. From looking around this is possible from a USB (with a Casper RW loop file I think). I have used the Live CD to create a bootable flash drive, which works on PC's but not my mac. Using these instructions: [URL] I was able to get my Mac to see the Linux at boot but once I clicked the Tux icon it would hang/ freeze. I let it sit for 10+ min and nothing happened. I started over (with a fresh formatting) and got the same results. I have reformatted the flash drive and am ready to try over. I think that I am goofing up in terminal steps as I am not use to doing that. After the last step in the terminal I get an error, something like invalid number or similar, it is not the one mentioned in the instructions.
I know that this for advanced users, I am not yet but working that way. I an a (retired) power windows user, moderate Mac user and a new Linux user. I want to learn which is why I am asking. I am not in a spot to install Linux directly on my Mac, so I I am seeking help to do it on a flash drive. I want the ability to run off any computer and I see this as I way to get there.

What command is executed when you plug in a USB Flash drive manually in the PC's USB port?I am pluggin in the device and it is automatically getting mounted in /media/ed7a753f-df88-4984-b65a-5d3a8cc2714a. After I unmount the device using umount /media/ed7a753f-df88-4984-b65a-5d3a8cc2714a, how do I remount it from the terminal so that the weird directory gets created automatically and the Flash Drive gets mounted there?Another question, where does the system get this ed7a753f-df88-4984-b65a-5d3a8cc2714a. Is it some kind of identification of the disk?

I have a 2GB usb flash drive and I wanted to boot a linux distro from it. My dilemma is that I'm having a hard time balancing size with quality.I've been going the virtual route so far in my linux studies but the variety with hardware is so limited. If I had a bigger flash drive it wouldn't be a concern but I need to make do with what I have.So what's a good learning distro that has good features but can be installed onto a 2GB flash drive? I'm sure there is more than one but I'd like to get some different input from more seasoned users.

I recently used a flash drive to try MeeGo on my netbook. Unfortunately, the application I used to write MeeGo to the flash drive created a new partition in a rather unusual format. The Ubuntu disk utility can't delete the partition, and GParted can't even see it. How can I completely wipe the flash drive from Ubuntu? I'd prefer not to install any additional software.

System: Linux flashvoyager 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11 07:54:58 UTC 2010 i686 GNU/Linux Ubuntu 10.04 Installed onto 64gig Flash Voyager GTR plugged into Tosh satpro laptop dual core 4 gig memory. This is not a casper r/w persistent install version. This is installed directly onto the flash pen and running as if the flash drive was a solid state disc.
I have obtained a 64gig which can read at 34mb/s and write at 28mb/s. The reason I wanted this was so I could install linux ubuntu and run the OS straight of the flash as if it was a Solid state disc. I have tried using the pendrivelinux method where the persistent data is stored inside a virtual file system but I found it did not allow grub or kernel updates without the need to rebuild the entire datapen plus I did not know how to get rid of the live boot menu where it asks for language and the like.
I boot the pen straight into linux ubuntu 10.04 via the bios boot menu and select the usb pen drive. Once into grub I select the most recent kernel and then load up ubuntu. When I first started using the distro from the pen the speed of the web browsing was so slow. I have since configured the browser to store the cache inside tmpfs /media/ramdisk and browsing seems fine now however there is underlying speed issue with using the method of install. Uncompressing installs takes an age. I have configured fstab like so:
#System
proc /proc proc nodev,noexec,nosuid 0 0
/dev/sdb1 / ext4 errors=remount-ro 0 1
[code]....
PS: I am not allowed to use the HDD on the laptop since it is company laptop. My previous company laptop had Kubuntu 8.04 with XP as VM. Also having the install on the flash drive would give me the convenience of booting the pen from any hardware.
