CentOS 5 :: Using USB Flash Stick As Boot Disk
Mar 20, 2011
I would like to use a USB flash drive as a boot disk. I have 2 hard drives. I will have Windows 7 as Drive 1 and Linux as Drive 2.I would like to not touch Drive 1 at all NO grub or other boot-loader. My old system I used a floppy drive as a boot disk.This worked if floppy was inserted: It booted grub giving me the choice of Windows(drive 1)or Linux(drive 2). I would like to replace the floppy with a USB stick. I have a couple of 64 MB (LOL) flash drives to use.

I'd like to move my existing Ubuntu installation from my hard disk (/dev/sda1) to a USB stick. How do I copy the data from HD to USB? dd is obviously not the right option since the HD is 320GB and the USB stick only 16GB. However, only 3.5GB are used so this makes perfect sense.And it would make my HTPC even more silent |-)

I have a IEI IBX 530 unit that uses a flash disk for storage. I used a Transcend 32GB flash disk and installed CentOS 5 successfully on the unit. I now wanted to install a second unit, but am using a SanDisk Extreme IV flash disk. The installation completes successfully, but when the system reboots for the first time after the install is complete, I get an error: "Grub Loading Stage 2. Read Error". This error occurs using CentOS 5.3 and even occurred when trying Fedora 9 and 11.
why this is occuring ot how I can resolve it? I used both the 16GB and 8GB Sandisk version, and created partitions as follows:
/boot (100MB)
swap (1GB)
/ (remainder of disk available)

I recently acquired (another) older laptop in need of a hard drive. Lower capacity IDE laptop drives are getting hard to come by from reliable sellers. I'd like to rewire a USB port, and run it into the hard drive slot, running the system off a flash drive rather than a hard drive. I'm running in to the problem I can't find any way to set it up. The system does not support any BIOS options for messing with USB drives. Why it CAN boot off one is beyond be, it's not in the temp boot menu, but when I leave it in, it boots off USB by default. I tried loading Ubuntu, and I have tried copying the files off of a setup hard drive to the flash drive, but I have yet to be successful. Is it even possible to run a linux off a flash drive so I can keep a desktop environment, rather than having it reset to the default ISO state every time I reboot?

I have an 8gb USB Flash Drive. I am trying to make a Xubuntu 11.04 boot disk from it. I have done this once before with Ubuntu, but not Xubuntu. The problem is that when I go into the Startup Disk Creator, I get this error and the process stops. This is what the Flash drive file structure looks like after the process stops.

I wanted to install a Linux distro to a flash drive so that I can have a portable OS with all my settings, programs, etc. wherever I go. So I fired up a Linux Mint Live CD and installed Mint to the flash drive, and this seems to work OK. But now, whenever I try to boot up my system normally without the flash drive plugged in, it doesn't seem to work. It basically hangs for a bit, and then I get the following prompt:
However, when I try powering my system up when the USB is plugged into the computer, it gives me an option between using the OS installed on my USB and the OS installed on my HD. Selecting the latter, everything loads up just fine. I'm guessing that installing Mint to the flash drive somehow messed with my native Grub installation.

I meet a problem about "Your boot partition is on a disk using the GPT partitioning Scheme but this machines cannot boot using GPT." in installation. Does GRUB-0.97 on CentOS 5.4 support GPT?

I am trying to install Ubuntu 10.10 from a USB flash memory stick. It works fine until around 95%, where I get the following warning/error:
[Code]....
I click OK and the installer seems to finish nicely, except the terminal throws several errors along these lines (see photo):
[Code]....
I tried also with 10.04 LTS, the difference being that the install warning appears two or three times instead of once. Some results from googling (Ubuntu Forums, Ubiquity bug) suggest unchecking the initial update options. I am going to try this but I'm not sure if I'll be able to get the boot loader right (there seemed to be problems with this).

I'm trying to create several Centos virtual machines to run Cpanel servers on each. Centos 5 looks good due to bundled Xen. Not sure whether to go for 64 bit version of Centos 5 and run some of the Apps as 32 bit and a few as 64. The h/w is a Dell poweredge R710 with dual 2.26 GHz quad core Xeon procs, 5.86 GT/s 24GB ram memory speed 1067 MHz. Raid with perc 6/i.
I burned the Centos 5 iso onto cd-rw but my lap top and the new dell won't boot from it. I viewed the readme file which seems to suggest burning "boot.iso" on its own but that doesn't work either. A boot menu on the Dell has an option to "Deploy" an O/S. Do I need that or can't I simply boot from cd-rw? I used Nero to burn the cds. I asked Nero if any special box needs to be ticked to write a bootable image and they said no.

A Twist on the Boot Installation USB Flash Drive Have made numerous attempts at making a bootable installation USB Flash drive for CentOS 5.5 but in one way or another they all came up short.Using dd to apply bootdisk.img to a flash drive per the installation instructions seems to take over the entire device even though it only needs about 10 megabytes.Using the method outlined in the Wiki article Set Up a USB Key to Install CentOS and other similar methods causes vmlinuz and initrd to load very slowly. About 50 seconds compared to normal of less than 10 seconds. The dots going across the screen is like watching paint dry.Data partition not accessible to Windows machines.
The following adaptation of the Wiki content article Set Up a USB Key to Install CentOS by Phil Schaffner overcomes the aforementioned short falls. Much thanks to those who created the original content sources and processes. None of the following is originally mine. I just altered it a bit to overcome the aforementioned short falls.
Overview: Objective of the following procedure is to create a CentOS bootable flash disk also containing install iso and kickstart file, that does not suffer from the aforementioned short falls. Partition 1 Installation iso, kickstart file and anything else such as post install scripts, etc. Partition 2 Boot Partition ~15 megabytes.

I want to install 11.3 on a usb flash stick on a netbook.the internal harddisk should be completely unaffected, meaning
- when the usb stick is plugged in, bios should boot 11.3 from the stick
- when the stick is not plugged in, bios should boot from the internal hard disk
I am unsure how the boot options in yast have to be set to achieve that.I changed the order of the harddisks to /dev/sdb (=the usb stick) being the first.I selected /dev/sdb3 (The root partition of the to-be-installed 11.3) as user defined root partition.do I have to select "start from MBR" and/or "start from root partition"? is there more to do to make the usb stick bootable?

I installed Kubuntu 8.04.2 Live CD on a USB flash drive using a software program called Unetbootin (from Gentoo), and I can successfully boot into the OS with no problem but I am not able to save any changes such as preferences, because once I reboot, everything I changed or installed is lost. I guess this is because the OS is dumped into RAM and all of my changes were made in RAM instead of the USB flash drive.
My question would be is there a way (keeping my present configuration) I can save any changes to the USB flash drive so that when I reboot, the changes will stick?

I probably have not done any serious programming for 20 years, not counting a little HTML.
I stumbled onto an old FREESPIRE disk my bro sent me several years back -- and tried installing it on a Sony Vaio PCG FRV 28 I had crashed a few years back. The Sony bios is still aboard, but old enough to not have USB "booting" as part of the boot menu. I don't even know if one can easily hack into the BIOS on an old sony Vaio but changing the BIOS would solve lot of problems.
Does anyone have any ideas or certain knowledge on rewriting or modifying the Master Boot Code or an idea on making my USB [with Ubuntu or any other Linux implementation visible] and bootable to the bios on powerup?

I'm trying to get the built-in reader on my system working. It's one of those multi-slot ones on the front of the box. The card I have is specifically a "San Disk Memory Stick PRO Duo", this sucker here: [URL]
The light on the reader will light up, but there's zip in any of the kernel logs. I tried the obvious kmods to get it working - tifm_7xx1, tifm_sd, tifm_core, via_sdmmc, mmc_core, etc but no luck.
Nothing seems to be useful in lspci or lsusb:
Code:
00:00.0 Host bridge: Advanced Micro Devices [AMD] Unknown device 9601
00:02.0 PCI bridge: Advanced Micro Devices [AMD] Unknown device 9603

I recently purchased a camera with a 2GB Mini SD flash card. It has a usb card reader and works well. Is it possible to use that as a usb stick (disk) for installation? I want to burn the netinstall iso and also use the rest (partition the card) as storage for the camera if it can be done.

I have a USB which I would like to make the device boot able. I have looked into fdisk and it appears that using fdisk I can only set a partition to a boot able. Please have a look at the output of fdisk command. In the following the sdb1 and sdc1 are both USB Memory Stick. As you can see the sdc1 is set as boot but the sdb1 is not.
Code: Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I have searched and read threads about the Bitlocker, grub and TPM issues that might show up, but I can't draw any conclusions as some information contradict each other. To make sure I don't screw up my pc as thought I need to make a new post.
At work I'm supposed to run Windows 7 and encrypt the win-partition with Bitlocker. I have installed Windows, turned on the encryption and it ties into the TPM. But as I am moving over to the *nix department I want to run Ubuntu as dual boot to check everything rusn fine with all the systems I need. Before I installed Windows I partioned the disk:
1,5 GB for system/bitlocker requirement
147 GB for Windows, C:
85 GB which is empty where I intend to install Ubuntu (not formated yet)
I boot into Windows with my bitlocker/TPM key on an USB-stick. Without the usb-stick the pc won't boot. Now, before I try to install Ubuntu I want to make sure to do it the right so I don't mess up the Windows installation or won't be able to boot the pc at all.
There seem to be several "schools" to this. Some suggest I should have installed Ubuntu first, then Windows and then encrypt. Some say, no worries just fire away and install since you are not planning to read the windows-partition from Ubuntu. Or an alternative, install but make sure to deactive the encryption during installation. Some say, install but make sure grub is installed in (multiple choices) location.

I have a USB flash drive, which is bootable and I would like to copy the whole drive to a different drive.Can I just do a low level dd copy between both USB memory drives, or do I need to make an ISO of the source, and then put that ISO on the destination? I figured I could ask in less time than trying, and exhaustively testing to make sure I had it right...

my Fedora 11 system is not starting anylonger. It stops with the message:
Code:
VFS: Can't find ext4 filesystem on dev dm-0
The system told me since a while, that a lot of the sectors of one disk of the (software) RAID compound are failed already. So tried to disconnect each of the disks and start them separately. Unfortunaltly this is not working (for one its is not working at all, the other wents the same far as with both), when I tried to recover the system with the Fedora DVD, it said no distribution found. I am quite new and do not know so much about linux system, so i do not know what further information you could need. Maybe it can be important, that both disks are encryped (the system wents so far, that I can type in the password).

I installed Debian on my PC with a Acer Stock motherboard (xc600) with amd64 and after the installation finished it told me to remove my installation media and reboot. After reboot I was returned this message ' ERROR: No boot disk has been detected or the disk has failed.'. I have verified with gparted using mint live OS that I have Debian installed on my system.
I got believes that this may have be caused by a broken grub or I need to configure something I don't know how in BIOS.
I will update the topic later..
My installation media was a USB 2.0 flashdrive with a Debian 8.2 Jessie Installer and 9 different Linux distros. I have installed Debian multiple times before on my laptop and never had this problem so I know how to go through the installation process and set the partitions.

I have a (slightly complicated) dual/multi boot system.
I keep getting boot errors (when choosing ubuntu from the grub2 menu)
Code:
Serious errors were found while checking the disk drive for /boot
If I switch off and restart, ubuntu will then start without issue.
My setup is like this ....3 disks, one with 10.10 clean install - so Grub2, separate partitions for /, /boot and /home, one with windows 7, one with windows XP and 10.04 wubi (this is my old disk which I will trash once I'm happy with my upgrade to 10.10 & 7 on separate disks.
I installed 7 and 10.10 with ONLY their disks installed. After both were working, I added all disks and rejigged the grub2 menu (using update-grub and StartUp-Manager).
This problem only seems to occur if my previous boot was not 10.10 ( I will investigate this further). It's as if something (grub2 ?, the bios ?) is remembering part of the previous boot and not using the grub2 menu completely.

So I've been running Ubuntu in a VM environment for a while, seeing if I like it. I think it's something I'd like to have as the primary OS on my netbook, so I downloaded the latest Netbook Remix version (9.10). Problem is, I can't get the thing to boot from my USB stick. Before we get into any lessons on how to set up a USB stick to be bootable, and how to adjust the BIOS's boot priority... let me say that I've used this exact stick and this exact laptop in the past just fine. When my netbook came home from the store with WinXP on it, I created a Live USB using unetbootin v3.56 and made the stick bootable with a gparted-live ISO. I used this to boot from the stick and partition my drive in half so that I could load the Win7 RC onto the other partition. Everything worked great then. I blew away those partitions and went back to a single partition when I loaded up my full Win7 OS a few weeks ago.
I'm wondering if it's possible that Win7 does something special with the bootloader to prevent this stick from being recognized? I know that sounds kinda far fetched, but I have a vague sense of having read this somewhere, but I can't find anything along those lines now. Just to be sure, I went into the BIOS and took out both the CD and the HDD from the boot sequence, so the only thing in there was the "removable device". However, when booting from the stick in this configuration, I got a "please insert an operating system" type message. When I started this process, the stick was still in "LiveUSB" mode with the gparted OS - however, I didn't test it in Win7 to see if it would have booted from it. I just assumed that it would have since the last time I used this USB stick, it was to boot into gparted-live.
