Ubuntu Installation :: Bootloader To Usb Hard Drive - Error "no Boot Sector On Usb Device"
Apr 8, 2011
I am trying to install Ubuntu to an external usb hard drive (WD Elements SE). I am also choosing to install the grub bootloader to this disk (/dev/sdb) because I do not want anything modified on the internal drive. The installation appears to go okay, but when I try to boot to the usb drive, I get the error, "no boot sector on usb device" and it immediately falls back to my interal drive. I have tried this installation with both 10.10 (amd64) and 11.04 (amd64). How can I fix this?

My old Dell Inspiron 9300's CD Rom is no longer working. I've written the files to my 8GB USB device, and attempted to boot from it. Whenever I try, I get this "No boot sector on USB device". I'm also using Mac OS X to make the USB drive.

I am helping my pal to get into Debian (yes first timer).He is running W7 on a 500G SATA HDD and he has another 250G SATA HDD that he wants Debian to go to.Will Debian install grub on the master bootloader even if the installation is going on a separate hard drive?I have dual boot before but on the same hard drive.

I have Ubuntu/Vista dual boot desktop with Single HDD (200GB) that i cloned to an external USB HDD (320GB) using clonezilla. My intention is to use the external HDD as a backup to up running in case my 3 year old desktop HDD fails. To make sure the clone is good to use if need, i connected external HDD to USB port and tried boot from it but got "Error 18". I tried to Google got some infoDid a fdisk -lu and got the following.
Code:
Disk /dev/sda: 200.0 GB, 200049647616 bytes
255 heads, 63 sectors/track, 24321 cylinders, total 390721968 sectors

I've been running Debian Lenny kernel 2.6.26 w/ desktop kde3.5 on my laptop for a while, and im going to take a trip in which i will be unable to take wmy laptop with me. However, where i am going contains computers and i figured if i could install debian onto my external harddrive, i could just boot onto the other computers. I install it using the debianlenny-i386 dvd image. However whenever I try to boot it from a computer. Grub returns
Code:
Grub Loading...
Error 21
and then the blinkng cursor. On one site i found something saying "you may need to activat the drive" and some command-line instructions on how to do it. However the commands have faded from memory and i am now unable to find that site again. Could anyone offer insight on how to fix this "grub error 21" or how to activate it. I run primarily debian but i have a windows partition on one of my relative's computers.
Thank you in advance for the help!!!
btw I'm installing on a western digital 500gb "passport" external hard drive with ext3 and swap partitions.

I just upgraded to Fedora 11. (I decided to give 64bit a try and I am extremely impressed.Not one problem at all! Kudos to the devs.) Whenever I log in I get the Palimpsest Disk Utility telling me two of my hard drives have a reallocated sector count.I have two 1.5Tb Seagate drives (model #: ST31500341AS). One is a backup of the other. On the first disk the disk utility tells me I have 22 reallocated sectors and 53 on the second. I've been on Google on discovered that there is no easy way to fix this and that a few bad sectors are okay but too many is a sign of imminent drive failure. This obviously concerns me because both my main drive and its backup are showing errors.
I went to Seagate's website and downloaded their diagnostic software (Seatools for DOS) and it passed both of these drives.So, questions: is it possible that Fedora is giving me a false positive? If not, is 22 and 53 sectors something to be concerned about? If so, should I contact Seagate and see if I can pull warranty on these drives? Is there a way to repair this damage?

It all started about a week after upgrading to Jessie and I had an unusual system failure, in that the CPU went to 100% usage and the hard drive light was on constantly. The keyboard and mouse were were non-responsive. Not having REISUB enabled I did the "stupid" thing and pushed the reset button on the computer. BAD BOY! As a result the computer would not boot and I had to use a live CD to format the drive and install Wheezy (I had the CD).
After installing Wheezy, everything worked well for about 3 days and then it did the same thing. Fortunately I had REISUB enabled and was able to reboot. I looked at the syslog and found a segfault with colord-sane and, after some research that suggested colord-sane might be a problem, I set UseSane=1 in colord.conf . Things seemed to be okay for about 4 days.
Well, after all that I had another problem today with booting. During boot I got an error message saying that there was some hard drive problem and that I needed to log in and run fsck, which I did . There were I believe 4 INODE errors that I was asked if I wanted to repair, to which I responded yes. After that the system booted correctly. After booting and entering the Gnome Classic desktop I looked at the Disk Utility and checked the SMART data. There is now 1 bad sector where before there were none. The drive is a one year old WD 500GB Velociraptor.
Don't know if this is relevant, but in the days before this latest "crash" I had downloaded about 8 movies using bittorrent. Could this have overtaxed the HDD?
I guess my questions are: When fsck "repaired" the disk would it have moved any data from the bad sector to a new location? What may have caused the sector to go bad ? Should I be buying a new hard drive?
The system seems to boot okay,at this time, so I assume that no critical system files were affected. Just curious as to how I should proceed. First is BACK UP my data. Got that !
One more thing I just thought of is that every time it "crashed", I was using LXDE.

I'm writing a C program that reads the boot sector of a USB disk. (it is mounted as /dev/sda1). I'm able to read the sector, by the calls code...
The problem is when I wish to write. I use the call:
bytesWrite = write(fd, buf, 512)
The 'write' returns the value of 512, which looks as if the write was successful, yet
when I read again the /dev/sda1 device, I see that no writing was actually made.
Can anybody tell me what do I need to do in order to allow an actual write to the
device?

I have minor problem with upgrading a hard drive. I am running an old pentium lll with two hard drives. On the first hard drive I have two partitions of around 90GB each. On the first partition is installed winXP and on the second partition I have Suse 10.3, both booted by grub and living happily side by side. My second hard drive (which is formatted for windows is only 4GB.
My problem arises when I try to replace the 4GB with a 80Gb hard drive. When I disconnect the 4GB drive the system fails to boot up and complains with error 21.

I have an audio recorder that doubles as a music player. It can play WAV files. So I put in some WAV files and they are out of order, even if they are named numerically. Read somewhere about a little CLI software called fatsort so I installed. The device is located at /dev/sdc. So naturally I write fatsort /dev/sdc, it says something about permission. So sudo fatsort /dev/sdc. Thing is, it says:
Code: sort_fs: Device or resource busy! If I "eject" it (unmount) then it says something about cannot read boot sector or headers. On Windows there is FAT Sorter. It does not work in WINE. So every time I put something in, I have to get to a Windows computer to sort it. It seems like fatsort is the only program that sorts FAT systems in Ubuntu/Linux.

The external hard drive which contains all my photos and where I backed-up all my important documents is no longer recognized. It is a three month old 500GB Iomage Prestige Desktop Hard Drive.When I plug it in, it is recognised as a USB device, because it shows up when I type lsusb, but dmesg gives this error message.
[19712.013250] usb 2-2: new high speed USB device using ehci_hcd and address 21

I popped the disk out of the casing put it on a SATA connect internally and then tried the file recovery programs testdisk/photorec and SpinRite, but both failed because they couldn't recognize the external hard disk.

So when i install ubuntu it gets to 47% and than i get this error message. After that the install doesn't really seem to do much.Code:Device /dev/sbd has a logical sector size of 4096. Not all parts of GNU Parted Support this at the moment, and the working code is HIGHLY EXPERIMENTAL.Now i did search and i found another topic where someone had the same problem. His solution was to reburn the CD and try again. I did that and it still got me the same messageP.S. I do have two boot options now however. One for ubuntu and one for windows though i already ran the uninstall.

Upon installing Fedora on my Samsung NC10, I loved it. It feels stable and isn't cluttered with pointless apps. However I was immediately greeted by Palimsest Disk Utility warning me that the 'reallocated sector count' on my hard drive is going bad. I'm not too sure what any of it means but here's the statistics;
ID: 5
Attribute: Reallocated Sector Count
Current: 100
Worst: 100
Threshold: 10
Value: 1 sector
Status: failing
type: pre-fail
status: updates
It also says the temperature is 46 degrees yet the netbook's taken to being very, very hot around the touchpad and under the hard drive.

I'm trying to create a dual boot with ubuntu 10.10 on my acer laptop with windows 7. I looked at my hard drive and I found out that it has three partitions, one called System Reversed, another one called PQSERVE or something like that (which is a recovery partition since acer laptops dont have a recovery cd), and the third partition is C:.
So I shrunk my C: drive, and created a 44gb partition for ubuntu, and a 6gb swap. I then booted with the ubuntu cd and went into manual partitioning. I selected the 44gb partition as "/", and set the 6gb partition to swap. The problem is at the very bottom of the partition manager, where it says "Device for boot loader installation". I get several choices, and I'm a bit unsure which one to choose.
The choices are as follows:
/dev/sda ATA WDC WD5000BEVT-2 (500,1GB)
/dev/sda1 Windows Vista (loader)
/dev/sda2 Windows 7 (loader)
/dev/sda3
/dev/sda5
/dev/sda6
My first thought was of course why do I have a vista loader? I don't even have vista!

I was using the disk utility on Ubuntu 10.04 and wanted to make by 500GB external NTFS formatted USB drive into 1 x 50GB FAT32 and 1 x 450GB NTFS. I clicked the option that said format or create a partition and it basically wiped the whole thing in a split second leaving me with 500GB of seemingly empty space. Obviously the files are still there but I cannot boot the drive to view anything. I have downloaded testdisk, but don't know how to use it, but I am sure there is a relatively simple solution here. I am currently repairing the boot sector of the drive as Test Disk showed the drive as "no type" i.e. not FAT/NTFS/ext4 etc., but shows the correct amount of used space though, but I cannot view anything err go, I cannot use the undelete command as yet.

I've tried installing Ubuntu from the installation disk, flash drive, and using windows installer. The drive and disk said I didn't have enough memory open to install (I have 160GB open)upon looking around in the demo, i noticed that it couldn't find my hard drive as it wasn't on the drive explorer. So i searched for answers and found a few possible ones but i wanted to find someone with my exact problem--Couldn't find any. So then I came upon the Windows Installer and Tried it out. All went well until i had to reboot, it said it couldn't find the installation.iso (which is indeed on my computer) and that i should run "Chkdsk /r" and i did. Nothing changed. I still believe that Ubuntu can't see my hard drive when windows can, why is this? Is there a way to fix it? EDIT: How could I forget to mention I'm on Windows 7?

I recently put together a computer with scrap parts that I have. It had no operating system on it at all. I downloaded Ubuntu on a different computer and burned it to a CD (I also verified the hash). I put the disk in and followed the instructions. Then when it wanted me to take the disc out and reboot I did so and clicked ok and it rebooted. I changed the boot order so that 0-HDD was first, and it said that the disk failed and wanted me to put in the system cd. Anybody have any solutions?

I have an Acer Aspire One ZG5 netbook. I have Windows XP home installed. I downloaded Ubuntu 10.04 netbook edition and put it on USB drive by Unetbootin. I booted from usb and it worked perfectly. I then installed Ubuntu to my hard drive from the live desktop and nothing went wrong. Perfect so far. Next, i shut down my netbook and took the usb drive out. I booted my netbook and it started loading Windows XP, didn't ask me if i want to use Ubuntu. I shut down the computer and pressed F5 while booting. It asked me what i want to do. I selected 'go back to OS selection' and i could only choose Windows XP from there. It was the only thing i could choose.

I can boot and run the live CD "ubuntu-10.04.1-desktop-amd64." Verified checksum and is ok
When I install it via CD or after running in CD mode and installing from the desktop the system will not boot. 250gig SATA drive.I can't for the life of me get it to boot after installation. It keeps dropping into 'initramfs' I even tried installing "ubuntu-10.04.1-server-amd64" and get the same result.Is it something to do with the SATA drive?

After lot's of research i still can't find any solution to my problem, that's why i'm posting a message here.So, it's been few days now that i'm trying to install ubuntu 10.10, with the live CD, but each time when i must choose where to install it or how to make partition, it just tell me there is no hard drive..(i have two 1 TB sata hard drive )So i tried many things, GParted doesn't find my hard drive either, they appear in the bios (i can run windows), try to uninstall a raid program that might hide the hard drive, but it didn't work either.
So i came to see that i had Marvell 9123 which seems to be a SATA controller, and few people seems to have some similar issue with that Marvell stuff..I'm quite desperate now.. i tried to install ubuntu on a USB drive but my computer just doesn't boot on it (i tried this method for the sb drive URL...

I have the DVD installer of Fedora 10, i want to dual boot with windows vista. well i get up to the partitioning part of installation (in anconda) and it asks me how i want to partition it... i wanted to re size my partition and create the default format, so i keyd in 70GB and Okay. then it came up with an error, saying I had bad sector(s) The error told me to run chkdsk /f /r in windows, then i could run ntfsresize with -b, (in Linux) well i did all those steps, and shrunk /dev/sda1 to 70gb (/dev/sda2 is my recovery partition) i have a 140 gb hard drive, but can't find the unallocated space anywhere!
when i booted windows, it ran a chksdk, like it should, and in my computer it said that it had been shrunk (because the pie graph showed a capacity of around 70GB) When i go into windows disk management it says no unallocated space, just one big partition (and a 8gb recovery partition) this is the same with GParted on puppy linux, GParted on fedora 10 (live cd) says there is no drives I can mount or unmount and same error on partition logic... in EASUS partition manager i get told that there is no unallocated space, in the fedora installer there is only /dev/sda1 and /dev/sda2. Does anybody know.. how to install fedora on this partition, or get rid of the partition and repartition it another way. when i click on the option to remove all linux partitions and create default format, it errors and says it cannot make another primary partition, then says there is no room for /boot. and i can not proceed.

When I installed, I accidently installed the bootloader to the mbr of my hard drive instead of the Ubuntu partition.Is there any way that I can make it so that it shows the Windows bootloader first? (Windows partition is set to active, Windows is on hdd0,sda1, Ubuntu is on hdd0,sda4 with sda5 as swap)

I'm running 9.10 off of a 4 GiB CF card. I keep running into space issues with updates, so I purchased an 8 GiB replacement card. I've cloned the 4 GiB card to a .IMG file using DD.I've then copied the 4 GiB image back to the 8 GiB card using the Ubuntu startup disk creator program. Once done, I'm able to properly boot off of the new 8 GiB clone.Unfortunately, the clone ends up with 3.67 GiB of unallocated space at the end *see attached). I tried deleting the "extended" partition that the swap is located at after booting from a Live CD and the system was unable to boot after this. I was thinking that I would delete the swap entirely and create a swap file after I merged the existing partitions, but I was unable to do this.
best way to do this (e.g. get one large 8 GiB partition with my old image on it)? I still have the original untouched 4 GiB card and also have an external CF drive if I need to redo the cloning. I've also used Clonezilla before, so perhaps there's a way to do this that allow me to grow the image as it's being cloned.
