May 11, 2010I have a rather puzzling error. I recently purchased an usb external hard drive with the intent of installing Ubuntu on it. I have had great success with installing various linux flavors on usb thumb drives but I need a little larger space for engineering applications that I use. Anyway, I removed my laptop's internal hard drive and installed ubuntu 9.10 on a recently formated external hard drive. Everything worked fine at first. Upon restarting I get an error that says "no boot sector" and it asks to hit either f1 to retry. When I hit retry, Grub loads most of the time. Occasionally it does not work. Is Grub just not installing correctly? I searched for this error but I found nothing that directly applied.

Mar 24, 2010I currently have a mirror raid array with 2x 1TB HD's (Western Digital Caviar Green WD10EADS SATA). They are both the standard 512 byte sector HD's. I just ordered a new 1TB Hard Drive (Western Digital Caviar Green WD10EARS SATA) as I want to wipe the current mirror raid and use the 3 disks in a raid 5 array.
But to my suprise, the new 1TB HD is an "advanced format" HD with 4k byte sectors... Am I screwed or can this 4k byte sector HD be used in a software raid 5 array along with the 512 byte sector hard drives?
(The WD hard drive says you can jumper it to work with XP which can only use 512 byte sectors... there's also a utility you can run that does something to make it compatible with XP too.... Makes me wonder if these new drives are backwards compatible?)

Apr 21, 2011I have been running a dual boot system with Windows XP and Ubuntu 10.10 64 bit with the dual boot selected by Grub (placed y an Ubuntu install).
Recently I have installed Window 7 Home on a spare disc. My Bios allows me to select which disc to boot.
The Win7 installation has overwritten the boot sector on the WinXP/Ubuntu dic so that it is now not bootable.
I can sse all my Ubuntu files with a Live Linux Disc, so I can get all my files back.
Is there any easy way to re-install Grub or should I just do a clean install of Ubuntu, perhaps to a blank partition?
Ubuntu Installation :: 11.04 - Loading VM / Error Reading Sector
Sep 1, 2011I created a boot disc (USB drive) with Ubuntu 11.04 and tried to install it on my Gateway GT5012 desktop running Windows XP. It gets to the part where I can "Run Ubuntu from this USB," and I select it. The screen shows "loading vm/linuz..." or something like that, and then the entire screen turns into dots.
One time, when trying to boot from the drive, it brought up
"CHS: Error 0201 reading sector 1418005 (88/68/3)
EDD: Error 4200 reading sector 1418006"
I ran this same USB drive on another computer (also running XP), and it worked just fine, so I really have no idea what's going on. If it matters, the computer it worked on had Internet access, this one didn't. It says "Loading /casper/vmlinuz..." and then goes to the screen of flashing dots.
Debian Installation :: How To Copy USB Key Boot Sector To HD

Hardware :: Advanced Format 4k Sector Drive With LVM
Nov 24, 2010So I finally bought an advanced format drive, the 2 TB Samsung f4. I will be using it on my slackware box, running slackware 12.2 with kernel 2.6.27-7. I intend to format the drive by hand with fdisk and start the first partition on sector 2048, or perhaps boot a livecd and format it with a newer version of fdisk or parted that will natively partition this drive correctly. My real question is, do I have to do anything special to add this drive to an existing LVM volume group? I'm thinking no, since LVM basically just breaks all your data into 4 MB chunks and spreads them across the pool of partitions you've defined, but I've found many conflicting opinions from searching google. To simplify things, I'm not using RAID of any sort, neither hardware nor mdraid.

Software :: Sfdisk Starts Partition From Sector 1 Instead Of 63?
May 1, 2011Slackware 13.1,using "sfdisk".I need to use this one as it can be used in a non-interactive mode,"parted"is not a solution for me.Inside my own script I make the partition like this:
Code:
# MAKING PATITION:
set `losetup -f`; dev=$1
`losetup $dev $out`
sfdisk $dev << EOF
,,$fsys
EOF
However after formatting this single partition in FAT16 I can see the drive in my emulated Windows311, but not use it. It says that the drive cannot be accessed. When I do the same thing interactively with fdisk it all works. When inspecting the partitions in both cases via "fdisk -ul" I see that whenever sfdisk is used to create the partition it is created starting from the 1 sector. Whenever fdisk is used it is created from 63 sector (which is correct of course). How can I make my sfdisk start the partition not from the 1st sector, but also from the 63 so that OS wouldn't have problem with that?
I tried like this:
Code:
sfdisk -uS $dev << EOF
63,,$fsys
EOF
But it then just says that the partition does not end on the boundary. Trying to see the content with fdisk -ul says that partition table is incorrect. So doing it this way doesn't work.

View 9 Replies View RelatedUbuntu Security :: 9.10 (64bit) - Symptoms Of Boot Sector Infection?
Oct 20, 2010I run 64 bit ubuntu 9.10. I recently rebooted my computer with a flash drive plugged into a USB port. My question is, could I have got a boot sector virus because of this? What are the symptoms of a boot sector infection? After the incident, I scanned the flash drive with clamav and it didn't detect any viruses. Also, in the BIOS, the hard drive is higher up in the boot sequence than USB mass storage drives. These two things suggest to me that a boot sector virus is improbable. But, recently, when I tried to boot into ubuntu, I got an error message saying that /dev/disk/uuid<some characters here> didn't exist.
Is this a symptom of a boot sector virus? So, I ended up re-installing ubuntu and I believe grub was written to the MBR. Will this have erased any boot sector viruses that were on my system? Can a boot-sector virus affect linux too? How can I check to see if I have a boot-sector infection? I also have windows xp on my computer. For some reason, windows xp isn't letting me install any updates, but this has been going on for since before the above incident with the flash drive and therefore I don't think that is due to a boot sector virus.
Ubuntu :: Disk Formatted In Error - Boot Sector Repair
Nov 20, 2010I 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.
View 2 Replies View RelatedUbuntu Installation :: Grub Fails To Be Written In Boot Sector / What I Need To Do?
Nov 21, 2010I am a complete noob at this and I need a hand. I was about to throw my computer out of the window when I decided to throw the windows out of the computer so to speak. So, I downloaded Ubuntu 10.10 and tried to install. I had a grub rescue after the installation (file system unknown), which I have seen discussed here. Being the noob that I am I decided to try 10.04 because it said it had full support. With this install I get a similar error during installation: grub cannot be installed in boot sector.
So, basically there is an issue with grub and the boot sector. I checked in my BIOS options to see if there was an option that prevented the writing of a boot sector or something, but I have not been able something like that. So, I am wondering if it is possible that Ubuntu does not really erase/format the selected disks or something, leaving any difficulty there.
Does anybody know? Or better yet: what exactly do I need to do a manual grub install?

Apr 30, 2011Been away from linux for a few years thaught id come back and give it a try again. I have Win7 on sda and installed 11.4 Ubuntu on sdb. Grub2 Over wrote the boot sector for windows so windows wouldnt show in the boot menu. I repaired that after some research and then tried it again with 10.4 LTS version of Ubuntu. Same thing. Now I've fixed windows boot sector a second time and im ready for round 3. Any hints on how to get grub2 to boot both OS's? Ubuntu 10.4 is still on sdb I think I should just need to re-install grub2 But how to do it without Killing the windows boot sector?

View 2 Replies View RelatedGeneral :: Encrypting External 4K Sector Drives Correctly
Jan 29, 2011I've recently brought a Western Digital Elements 2TB external hard disk and have been planning to encrypt it for use as a backup drive. However, it seems that these 2TB disks use the new 4K sector sizes and thus need to be handled more carefully than the older 512K ones.
After spending a week looking on Google, I have to admit I'm pretty confused and hope somebody here might be able to verify my conclusions
The drive reports that it's a 512-sector drive which is probably false. Using fdisk -uc, the original partition starts at sector 2048 so I assume that is a valid sector also to start a dm-crypt partition overwriting the previous one?
I've also read that every layer that is added to these drives must support the 4k layer. That means both dm-crypt and the ext3 filesystem I intend to put it on have to do so also.
Looking through the cryptsetup document, it states under the option "--align-payload" the following:
"Align payload at a boundary of value 512-byte sectors. This option is relevant for luksFormat. If your block device lives on a RAID, it is useful to align the filesystem at full stripe boundaries so it can take advantage of the RAIDs geometry. See for instance the sunit and swidth options in the mkfs.xfs manual page. By default, the payload is aligned at an 8 sector (4096 byte) boundary."
The fact that the payload is aligned at 4096 seems to indicate to me that it should be fine using default settings. Does everybody agree with this? Or do I need to take special measures due to the dm-crypt headers?
When I later finish up the dm-crypt layer, then I need to put ext3 on it. I understand adding -b 4096 to the mkfs.ext3 command will resolve that. Is that also correct and will it work well in combination with the dm-crypt layer?
