Ubuntu Installation :: Format Both Disks Before Reinstall?
Nov 19, 2010
Reformatting two drives before re-installation. I'm new to Linux generally. Can someone give me instructions on formatting the hard drives? I have installed ubuntu on a machine that had been running Windows for a while. Since Windows worked the boot drive for years, I decided to switch the positions of the two drives; putting the old data drive into the boot position.
Apparently, ubunta was too smart for me. I guess it discovered the Windows installation, and decided that's where it should be installed too. Now, what I would like to do - and I would really like to do it this way - is reformat both the disks, wiping out everything that's on both of them; before running another installation.
BTW: the old data drive is still NTFS, and I don't want installations own both disks - reformatting and starting fresh seems nice and clean, if not entirely necessary.

I thought that alignment of 4096-byte sector Advanced Format hard drives was automatically taken care of via Gparted or Disk Utility until I bought a Hitachi HTS547575A9E384 (Travelstar 5K750) and saw that Disk Utility showed my partitions to be out of alignment. I then realized that my WD, which I had bought a few months ago, probably had its jumper set to emulate a 512-byte sector legacy drive (512e) and is probably not set to the AF setting.
Straight to the problem.
I've searched many sites, some of which suggest using fdisk (others the proprietary software of the hard drive's manufacturer). It is essential that one change the arguments prior to changing the partition table as there is no way back (yet, as far as I know) without having to move data to another drive and starting all over:

I have built a couple RAID's, but I'm uncertain of how I should format the partitions of the raid. Should I format partitions on each disk, and then add them to a raid, or should I create a raid on unformated disks and then format the raid as a partition? Does it matter, and are there performance/reliability issues? I'm creating a RAID-5 using 3 SATA disks on RHEL for user data area.

I have/had a PC with several hard drives, and a mix of ubuntu and windows on multi boot.The old boot drive died screaming, and I need to start again. (But my data is safe! yay!)
Is there anything special about which drive can be the main drive to start booting from? Or to put it another way, can I install to any of the other 3 and expect it to work, or do I need to switch them around so a different drive is on the connections for the recently dead one?

How do I reinstall cent OS 5.2 without formatting the partitions? for example: I've create several partitions (create custom layout) and OS is installed completed. But I have some application need to reinstall at "clean" OS. If I delete and create same partitions again it take long time to format the partitions. How do I just reinstall OS without formatting those partitions?

So I was messing around trying to uninstall Nibbles and reinstall since I have an issue starting that game and something happened and removed the submenu under Games called "Logic", which had another whole list of games.
Is it possible to reinstall the games package or reinstall the update?I'm thinking more of the lines of a system restore or something so back 2 days from today.

the recent versions of fdisk on Fedora 13 and Ubuntu 10.04 are supposed automatically to solve these things around 4k sector aligment thing if one starts fdisk with -u and -c flags. But I'm getting confused as the heads / sectors informations always differ every time I create a partition.I have WD Green 1.5TB disk. I want 2 partitions. sdb1 with 1.3TB and sdb2 with the remaining space. Here's how it looks like. When I create the first partition (1.3TB one), I get following listin with fdisk:
Code:
# fdisk -lu /dev/sdb
Disk /dev/sdb: 1500.3 GB, 1500301910016 bytes
78 heads, 37 sectors/track, 1015342 cylinders, total 2930277168 sectors
Units = sectors of 1 * 512 = 512 bytes

I have servers which contain SATA disks and SAS disks. I was testing the speed of writing on these servers and I recognized that SAS 10.000 disks much more slowly than the SATA 7200. What do you think about this slowness? What are the reasons of this slowness?
I am giving the below rates (values) which I took from my test (from my comparisons between SAS 10.000 and SATA 7200);
dd if=/dev/zero of=bigfile.txt bs=1024 count=1000000 when this comment was run in SAS disk server, I took this output(10.000 rpm)
(a new server,2 CPU 8 core and 8 gb ram)
1000000+0 records in
1000000+0 records out
1024000000 bytes (1.0 GB) copied, 12.9662 s, 79.0 MB/s (I have not used this server yet) (hw raid1)

I am attempting to install ubuntu 10.10-alternate-i386 that was burned on a cd.
Motherboard: SOYO SY-K7ADA v1.0-2AA1
Main Processor: AMD Athlon 1700+
Primary Master: WDC WD800AAJB-00J3A0 0.103E01
The HDD is brand new and hasn't been formated, partitioned, or previously had any other OS on it. The HDD is recognized in the BIOS.A list of possible drivers are listed in which don't match, except for two, but they don't lead to anywhere beneficial in order to complete the installation process.At this point, I have no idea how I must proceed.

I did a fresh install of 11.04. It didn't let me choose custom mount points for my disks, so I left non-system partitions unmounted in the installer. Big mistake. It seemingly screwed with two of my disks. I can see them in disk utility, but disk utility cannot identify partition information.
@fridge:~$ sudo mount /dev/sde1 /m2 -t ext4
mount: wrong fs type, bad option, bad superblock on /dev/sde1,
missing codepage or helper program, or other error

I've installed Windows 7 onto one hard drive, and then installed Ubuntu 9.10 onto a second hard drive. The installations seemed to go fine, and I can boot into Ubuntu from the GRUB menu. However when I try to boot into Windows from the GRUB menu, I get a message saying "error: no such device: 446e94786e946488".

Brand new HP Compaq Presario CQ56, want to dual-boot 7 & Ubuntu. Too many partitions I think:
HD0 - 298.09 GB
System
199 MB NTFS
C:
279.36 GB NTFS
RECOVERY D:
18.43 GB NTFS
HP TOOLS
103 MB FAT32
Want to add Ubuntu + Swap in the 90 or so GB range, fairly new to partitioning. Trying to create recovery disks using system tools is over 16 Gb, for that kind of expense I may as well just order recovery disks OEM if (When) Windows falls apart.

I installed ubuntu 11.04 inside of my Windows 7 using live cd. All was working fine until three hours ago when I started my pc and selected ubuntu, it gave me grub command line. I figured it was because grub couldn't find ubuntu. So, I rebooted from win7 and now all I can see is ubuntu.icon, wubi-uninstallation.exe, ubuntu and another folder. ubuntu/disk is missing.

I just installed Ubuntu server edition to my computer (brand new, no OS) and finished installation. In the terminal I used apt-get ubuntu-desktop to install a desktop interface.In my rig, I have two 500GB HDDs. I set them up through my computer BIOS as RAID1 drives, yet as I understand I still need to configure the Ubuntu software raid for it to work correctly. Unfortunately, I already partitioned my drives! I used the easy way (guided with LVM or whatever) and let it do it for me. Now, RAID1 is very important to me! Is there anyway to repartition the disks to use RAID1, or do I need to wipe my computer and reinstall Ubuntu?

I wanted to merge my 1TB disks into and RAID 5 array, 4 of them in RAID 5 is above 2Terabytes limit of msdos partition tables which grub2 can boot from, so I decided to start up the system from scratch, by building it on GPT partitions, but seems grub2 won't boot from GPT partition because it drops to grub rescue and I can't really do anything from there.
here's my set up:
/dev/md0 (raid 1) - 100MB total:
- dev/sda1, /dev/sdb1, /dev/sdc1, /dev/sdd1
/dev/md1 (raid 5) - 45GB total:
- dev/sda2, /dev/sdb2, /dev/sdc2, /dev/sdd2
/dev/md2 (raid 5) - something bit lower than 3TB:
- dev/sda3, /dev/sdb3, /dev/sdc3, /dev/sdd3
any tips how to have this system up and running? Because I've spent like 3 days jumping over various problems

I recently tried installing Lucid x86 on my system beside Windows 7 and managed to screw it up.
My disk setup is this;
Disk A = 3 partitions (1st partition=Windows 2&3 partitions=Data)
Disk B = 1 partition
Disk C = 3 partitions (1st partition=Data 2&3 partitions=Ubuntu & Swap)
Disk A = SATA and internal
Disk B = SATA to USB external
Disk C = SATA to USB external
I want to install Lucid on the 2nd partition on Disk C. And dual boot it with Windows on Disk A.
During Lucid setup i specified the partition for installation (C2) and asked for GRUB to install on Disk A (no partition specified) so GRUB is always used as the dual-boot manager even if the Lucid disk (Disk C) is ejected. Once installed and rebooted i was taken to the GRUB rescue prompt as no installation drive could be found (a long string of numbers (looked like a Disk ID number???) was also shown). Obvviiusly, i could not access either OS on my system at this point. I had my W7 DVD handy so it was just a case of recovering the windows boot manager and i could use my PC but how do i go about installing Lucid with this setup? Should i specify a partition for GRUB to install to? I have a hunch this is where i am going wrong but am too scared to try again and potentially balls things up.

So I installed Wubi with Ubuntu 10.04 and chose the standard partition size (8GB?) and now I am running out of disc space. How do I resize this partition?
This guide didn't help: [url]
How do I resize the virtual disks? The download link doesn't work and LVPM doesn't support 10.04.
Any other options or do I need to re-install the whole Wubi?

I'm running Ubuntu 9.10 Karmic Koala, and the latest kernel upgrade (xxxx.22) won't start the system because it can't find the hard disks. It ends up with a prompt from (initramfs).The computer has an MSI board with Intel P4 Dual CPU, and a Phoenix Award BIOS marked W7037 IMS V1.2, dated 091604 (Sep16/04). I doubt that a newer BIOS that will fix the problem, but if anyone knows I could try to find a floppy drive and a diskette, because they require that to install the newer BIOS (ver 1.3). Does any one have a better method? Is it still possible to get the previous kernel version until they fix this bug (if they ever will)?
Is there a way to change the boot sequence in GRUB2 so the original kernel would be the default even if the rest of the software has been updated? Since 10.04 has several bugs and annoyances, may be it's time to change to another distribution (I've tried Mint 9, but it has much of the same, like having to enter the password if I take a short break from the computer). Many questions at once, but less and less things are functioning with each new revision. For instance to use the scanner I must go back to 8.04, or use WINDOWS! (The scanner is the only reason why I have Windows on the computer).

used to run ARC linux and Windows 7 on my computer and i am now trying to install Ubuntu 10.10 X86_64When i used the live disc of Ubuntu 10.04 and load the installer it finds my four harddrive they way it should... sda,sdb,sdc,and sdd...When i however try the same with ubuntu 10.10 it displays my usb cardreaders drives first and then my hardrives as sde sdf sdg and sdh.I tried installing ubuntu with the reader unplugged and then reconnecting it after installation...But when i then boot with the reader attached it says it cannot mount drives sda,sdb,sdc and sdd becuase they are not ready.I think it is again detecting the usb cardreader before the sata controller ...Is there a way for me to alter the boot detection order so it will find my harddrives first and then the usb cardreaders ports ?

I bought an 1tb hard disk today and cloned my old 160gb ubuntu install to the new disk using gddrescue (from this tutorial [URL]) and everything worked fine. The problem is that I can't resize my home partition to fill the rest of the disk. I've tried using a live-cd and booting from my 160gb hard disk but I still can't resize the partition.
Here's the "sudo fdisk -l" output:
Quote:
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

I'm fairly new to Ubuntu/Linux. Here's the problem I'm encountering after I tried to install Ubuntu Desktop 10.10. I was installing from a CD, as I tried to install alongside Windows XP, (The setup detected 2 hard drives, the first one was 40 GB, with all my windows stuff on it, the other was a 160 GB one), I got the message "error informing kernel about changes made to .....", which would not disappear no matter what I clicked. So, choosing the seemingly only option, I force powered down the computer. As I powered it back on.
Windows did not boot, instead I just got a black screen of nothing but a flashing _. I tried booting from the LiveCD again, which worked well enough, EXCEPT, the 40 GB hardrive full of my Windows stuff and files was not detected, and the 160 GB drive was detected only in the drives tool, but not accessible. I have no clue as to how to: 1. retrieve important files from my 40 GB drive. 2. Restore Windows XP professional.

I would like to install ubuntu on windows xp which has 6 partitioned hard disks. When I try to install ubuntu on hard disk F, it says i need to select a root. However, I could not succeed in selecting a `root`. I also tried wubi, but it was terminated with an abrupt error just before it was finished. Furthermore, what does boot directory mean?

I have downloaded ubuntu studio 10.04 from torrent file available in ubuntu studio site.
1.Now I tried to install it directly from the iso as described here. It showed an error 'Can't mount the cd-rom' that is it couldn't mount the iso automatically.
2.Creating startup disk on my Seagate external hard disk (NTFS) didn't work out as 'Make startup disk' was greyed out.
3.Then I tried to install the OS from a pen drive. It proceeds fine until it hangs at 45% scanning disks in setting up the partitioner. I have waited for about 15 mins, but nothing happened.

I`d like to know what happens when with the disks the we include in the installation process of Fedora 15.Obviously, the HD we choose to be the system is entirely formated and reconfigured. But what about the others? What does happen to them? I`m asking this because I have included two brand new disks of 2 TB, one of them with 900.000 files and the other empty, both of them formated with ext4, and completely functional on Fedora 14. However, after the upgrade, in the very first Fedora 15 boot, these disks disapeared from "places", and could not be mounted even via terminal. Opening the Gnome Disk Utility, I found out they had been changed to VLM (instead of ext4) and that they also lost their original lable. I am starting to be concerned because all the data there was important to me.
