Ubuntu :: Installation - Important Active Partition To Be Unavailable To Work
Sep 9, 2010
I decided to have my laptop with dual boot. Already having Win7, I tried installing Ubuntu on another partition. While installation was in progress, during the step where we manually choose partitions to install ubuntu on, I was asked to provide a swap area for ease of operation. I provided another active partition for this supposing that this "swap area" is needed only during the installation. Unfortunately, as I found out later that this makes that important active partition to be unavailable to work upon both in windows as well as Ubuntu. I need to use this partition again.
I tried the "disc utility" in System--->Administration section to change the partition type to "hpfs/ntfs". After a longtime it showed me error (Unable to perform the operation). What could have gone wrong? I absolutely need that drive back, as it contains valuable media files.

I recently installed Debian 7.6 64-bit on Dell Vostro 1520 laptop.Using Gparted, create extended partition in the remaining disk space 67.91 GB
Install Debian 7.6 as follows
Code: Select all/dev/sdb5 / 8GB Ext4
/dev/sdb6 / home 17GB Ext4
/dev/sdb7 swap 5GB
I opened a terminal and ran some commands to show the results below....
Code: Select allroot@DELL-DEBIAN:/home/hugh# cat /proc/swaps
Filename Type Size Used Priority
/dev/sda7 partition 4979708 0 -1
root@DELL-DEBIAN:/home/hugh#
Code: Select allroot@DELL-DEBIAN:/home/hugh# cat /etc/fstab
# /etc/fstab: static file system information.
[code]...
I have a couple of questions....
1. Does the data above indicate everything is running as it should?
2. What does this command tell me about swap? "/sbin/swapoff /dev/sda7" I read somewhere it should be run on 64-bit system but not sure what it does.
3. Is the command "cat /proc/swaps" the best way to determine if swap is running ok?
4. Can I share this swap partition with another distro, e.g. Ubuntu or Xubuntu? as I would like to multi-boot for testing purposes.

I'm sure I've done this before and never ran into trouble so it's not like I wasn't thinking, just something went wrong this time and I'm screwed. I'll post a fdisk -l to show ya what I mean.
[root@localhost ~]# fdisk -l /dev/sda
Warning: invalid flag 0x0000 of partition table 5 will be corrected by w(rite)
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes

Well I tried to install Pclinuxos 2010 to the same partitions as Mint 7 and basically just over write it (this I have done before) but this time Pclinuxos says there is a bad block and it can't copy files to / (sda7) I didn't think much of it at the time and thought I would try to install it (Pclinuxos) on a separate 100 gb usb drive and it was a sucessful install.
After booting Pclinuxos I try to access my 1TB sda hard drive and I can ony access sda1 .....when I look at /dev/sda in gparted is shows the whole disk as unallocated.I have done nothing at this point in time other than what I just said because I am very afraid of loosing all my pictures and everything else on that disk....and for those that will say always back up ....if ya think I'm not kicking myself right now your dead wrong......

Yesterday I decided to install Fedora 13, having heard good reports about it. I started with linux back in the RH 5.2 days on which I cut my teeth. Since then I've used many distros and versions, openSUSE, RedHat, Ubuntu, Gentoo, Slack ... After the installation completed (without error), I rebooted at which time I got the following message at the grub screen: Quote: Error No Active Partition

I'm just setting up a partition on a seperate HDD in my system. I plan to use the partition to backup the important files on my main HDD (to guard against HD crash).
The question I have is about where would be the typical location to auto mount this partition? Which would it be normal to go for:
1. /backup/
2. /media/backup/
3. /mnt/backup/
4. /home/chris/backup/

I'd like to upgrade my 9.10 desktop to 10.04 but I can't get past step 1.I've done alt-f2 and issued update-manager -d, but no "New distribution" option is presented.I've clicked the "check" button and updated all my repo information but that doesn't help.I've done a wireshark trace and observed that the update-manager's requests get through the corporate firewall, and responses come back.Somehow it determines that no new distro is available.I'll explore further if someone could help me out with getting hold of the relevant update-manager source code.

Since last year I have this problem and it seems nobody knows how to fix it. Here is my post from last year, commenting the same problem [URL] Well, this is what happens to me. I insert my ubuntu/ubuntu studio DVD to my pc. It starts from the DVD and the first screen appears. I select "install ubuntu" and then it starts to load for like 5-10 secs.
Then another screen pops up, this one tells me to choose the main language, BUT.. i cant use my keyboard in this screen. It just.. Dies. I tried with like 5 keyboards, with USB keyboards and serial keyboards, it just happens everytime. I was an avid user of ubuntu studio back like 2 years ago, with my laptop, but with this PC (gateway GT4230m) i just cant do it anymore. Its very frustrating.

I grabbed Adobe AIR today, but it did not have 64-bit packages, or source. It claimed that you could install getlib(?), then force it to install with dpkg --force-arcitecture. I did so, and it runs fine.
Now, the Update Manager says that it cannot do a full upgrade. When I allow it to do a partial upgrade, it attempts to delete com.destroytoday.destroytwitter (the app I need AIR for.) Bottom line: Can I stop the Update Manager from removing this package? I can provide screenshots or logfiles on request.

I have had Hardy Heron 8.04 since 2008. Few problems, but when the red arrow indicated updates I clicked on it and it was for an upgrade to 10.04.I decided to upgrade but it didn't go well.I ended up with a black screen and white letters. I didn't know what to do.I don't know many commands.I posted here but got no response.I had no access to the Internet.I decided to reinstall Ubuntu 8.04 from the CD.At one point it asked me about a 10GB partition.I didn't really understand it at that point but clicked ok.When I got the computer running again I noticed that it was a new partition with 7 GB free space.What happened to all my precious other files?
I am panicking because I read a similar thread about a Windows/Ubuntu partition and the person was worried about losing all Windows files.I did back up the files on an external hard drive but not recently. Losing them would mean I had to make up a lot of work.

Fedora 11 was being run on a Toshiba Satellite Intel Core2 Duo @ 2.1 with 180 gig hard drive and 3 gigs of RAM. The laptop is encrypted, using Fedora's encryption option when installing 11. Just finished upgrading using the upgrading DVD. Fedora boots and runs fine, when update manager is accessed it says 338 updates available. When updating is attempted there is one unavailable package after another. Have attempted to break the updates down into manageable sections to no avail. There is no repository manager (that can be located). Where to from here?

I have just installed 11.2 i686 on two machines, one virtual and one physical. Both have been set to start in runlevel 3. For some reason it seems that my installations have missed some step in the process, because the system cannot find several rather important commands, eg. init and ifconfig.this is what I get if I try to run ifconfig:
Code:
user@computer:~> sudo ifconfig
sudo: ifconfig: command not found

This thread is not so much looking for a 'solution' as it is looking for some 'reason why', as I now have it working.I have just inherited a Gateway 509GE - P4 3.0GHZ / 1GB RAM / 200GB SATA WD2000JD HD. It is circa 2005 hardware. The previous owner had tried to install Mandriva after windows began to choke on accumulated garbage, then tried to revert to XP, both of which appeared to install but neither would boot. He decided to just get a new box and gave me this one.I ran Memtest86 and found a bad DIMM and replaced it.
I repartitioned and formatted, a single ext4 root partition plus 2GB for swap. I completely removed existing partitions including the hidden M$ restore partition and checked disk - all using Gparted Live CD.I put a full Slackware 13 on it, installed with LILO to MBR, rebooted... nothing... "No bootable device found".I booted to install CD and played with Gparted Live CD and everything was there and LILO configured correctly...I tried several times and looked at MBR sector directly - all OK as far as I could tell.
Long story short - as far as I can tell after trying a few things, I finally set the 'active' flag on the extended partition (sda1) and it now boots.But Linux does not care whether a partition is active and I have several boxes - including another with SATA drive that do not have any 'active' partitions. So I conclude this must be a BIOS thing looking for an active partition, but see nothing settable in the BIOS config (in fact very little useful in this machine's BIOS config).Anyway, it is now working but I would like to solicit any useful comments from others. Is it a Gateway thing? (This is my only Gateway box). Is it an SATA thing? Anyone else had to set a Linux partition active to boot

A few days ago my Laptop wouldn't hibernate in Windows 7, I managed to fix this problem by going into Windows' Disk Management tool and setting the C:/ Partition as the active partition, this fixed my hibernation issue, however I have just noticed that now when I boot my laptop my GRUB menu no longer appears, instead it just loads Windows straight away as if it was the only OS on my laptop.
I've confirmed it's something to do with my recent Disk Management change as I booted up GParted, removed the boot flag from Windows and when a rebooted my GRUB menu reappeared.
Not sure on how I can both have Windows as the active partition while being able to keep GRUB working also.
My Partition Setup is as follows:
/dev/sda1 C:/ Windows 7 (NTFS) (Boot Flag Set)
/dev/sda2 D:/ DATA (Documents and stuff) (NTFS)
Unallocated 1 MB
/dev/sda3 Extended 146.49 GB (LBA Flag Set)
/dev/sda5 Linux Swap 2.01 GB
/dev/sda6 ext4 20.00 GB
/dev/sda7 ext4 124.46 GB
Unallocated 10.00 MB
I'm running openSUSE 11.4

Is there any way to make a disk image of an active partition? I have to get a complete backup (partitions, MBR, all data files) of my server without bringing it down to do it. I want to have a backup that, in the event of a system failure of any sort, I can quickly restore onto a new, bare hard disk and have the system back up and running. The windows equivalent of this would be something like Drive Image XML, this is the functionality I am looking for.

I am running the latest ubuntu and I am having trouble getting networking sorted. I have 2 networks, one wired (eth0) and one wireless (wlan0). I connect to the internet using wireless. The problem is that I can only successfully connect to the internet if I disconnect from eth0. I have hit this problem with Windows machines and the solution was to adjust the "interface metric" in "Advanced TCP/IP Settings" so that the wireless was the preferred connection. How can I achieve something similar in Ubuntu?

I installed Ubuntu 10.04 with WUBI. In the setup wizard in windows, I selected the D partition to install Ubuntu on. It extracted the files, and after a reboot, and selecting Ubuntu, the Ubuntu setup wizzard appeared. After it was done, it rebooted. I selected Ubuntu, and this appeared on my screen:
Code:
booting from (hd0,0)...
And there it stucks! I tried editing C:oot.ini, to let it select the ubuntu files.
My original boot.ini file:
Code:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)WINDOWS
[Code].....
I have very little space on my system partition (C:) So, I installed it on D:. I'm using Windows XP Professional SP2.

After running Lucid since it's release I decided to wipe out my Karmic partition yesterday in order to utilize that space better elsewhere. So I booted up with the Karmic LiveCD, using the option just to check out Ubuntu. Then I opened up Gparted, unswapped (unmounted) the swap partition, made sure nothing else was mounted, and proceeded to delete my Karmic partition which then provided me with about 40 GB of unused space.
Since I wanted to re-assign 10 of those GB to my primary Ubuntu software partition where I keep all of my personal data, I went ahead and resized that one to make it 10 GB larger. First I had to move the empty space over which took several hours, but that wasn't a problem. Resizing the partition wasn't a problem either. Then I wanted to re-assign the remaining 30 GB to my Ubuntu boot partition which contains strictly my Ubuntu system ... and that's where the problem is.
The remaining unused space on the hard disk is located directly next to my Ubuntu boot partition. No matter what I do while using Gparted via the LiveCD, it doesn't seem to be possible for me to enlarge that boot partition. Does anyone know how I can do this either via Gparted, the Disk Utility from Lucid, or even via the terminal?

got a suspend problem with OpenSuse 11.3. I configured the powersave module that whenever I close down the screen of my laptop it suspends to ram. Works fine so far except when the screensaver is active. It just stays on when I close down the lid.

I have a 1TB WD Caviar green hard disk with Ubuntu 10.04 on it. I used a Gparted live cd to resize the Ubuntu partition and made two ext2 partitions 100GB each. When I tried to install Fedora 11 and told it to install in the free space it told me there wasn't any. I went back and deleted a partition, leaving it as unallocated space. It still wouldn't install! I downloaded Mandriva Linux and it installed in the unallocated space just fine. How do I get Fedora to install?

how to setup an Active/Active Load Balanced and High Available (If one of the nodes is down the system still runs) MySQL cluster. I have found quite a few howto's but I have some things unclear in my mind. I found a few solutions like this one: [URL] or this: [URK] Those are using two or four MySQL nodes, two Load Balancers to avoid a single point of failure but only one MySQL cluster management server. What happens if the MySQL cluster management fails?
I have also found a "MySQL Master-Master Circular Replication" technique but from what I read, with this option there is a chance that conflicts will arise if node A and node B both insert an auto-incrementing key on the same table.
