General :: Recovering/Creating NewWorld Partition On Mac G4 (PPC) After Botched Debian Install?
Apr 25, 2010
I was trying to install Debian 5.04 on a Mac G4, and in typical geek tradition, I didn't RTFM. During installation, I nuked all existing partitions, creating new to my liking. But as I learned later during the installation process, yaboot needed a NewWorld partition, so I can't boot the installation. I don't have any OSX CDs with me (this is a used G4 I purchased of craigslist) with which to create a HFS partition.I've re-run the Debian installer, which lets me create a partition that is supposed to be of type 'NewWorld', but the installer does not seem to like it or recognizes it.

So when upgrading to 10.04 there were a few errors and now the machine will not boot up. All I am trying to do now is recover some pictures from the HD so I can to a clean install. I used the Ubuntu 9.04 install disk to gain access to the HD and was able to backup some of the files but other files are locked somehow. When trying to copy them it says that "folder content could not be displayed. You do not have the permission necessary to view the contents." The files in question have orange X's on them.

I was trying to delete a logical drive in windows xp and the damn disk management tool in windows not only deleted my other windows partition but also my linux /data ext3 partition. Now I have a unallocated space in place of these partitions. The data is still there but the entries in the partition table have been removed. So how do I recover my partition. I was trying to use the following tutorial. [URK]
I used the sudo parted /dev/sda -- and then rescue START END command and could get back the /data partition. But it gives me the following error while mounting the partition. mount: wrong fs type, bad option, bad superblock on /dev/sda7, missing codepage or helper program or other error. In some cases useful info is found in syslog - try dmesg | tail or so.
What does this mean. How to I fix this? Also when I try to recover my windows partition using parted it scans for a while and then does nothing. It doesnot ask for writing the lost partition in the partition table. What do I do?

I didn't know a resize operation on a 750 GB disk was going to take 40+ hours, and I was biting my nails the whole time, until the power went out when "only" 8 hours where left.I can still mount the partition, and many of the files are still there, but some files show as '? ? ? ? ? filename.ext' with ls -l.If I try to go inside such a directory: Input/output error.

following problem. A friend phoned me in despair. Her Ubuntu didn't start any more - ASUS-Laptop switched on stops at a ramfs-prompt.
I started Puppy-Linux from DVD-Drive. Worked fine. But puppy can't mount her /dev/sda1 partition either. At least you can see that the partition is still there. Fsck stops with an error. May be the initial problem is a sort of bad hardware by which bad bytes were written to the hard drive. Hard drive and/or memory could be replaced but not the data.

I just ruined my /ntfs partition. I used the mkfs command and stopped it by ^C immidiately, but it was too late. mkfs.ext4 /dev/sdb1
Is there a way to recover NTFS partition now ? The partition </dev/sdb1> was 'ntfs' and mkfs.ext4 did not check if it was a ext4 or give any pre-check warning, just went ahead with making the ext4 fs on a ntfs partition.

Currently my system runs on two disks, sda 30GB and sdc 1GB. sdb is my data disk. I have set the partitions as sda1 /boot, sda2 /(root) and sdc1 /(swap).
Thinking that sdc was udma33 i used the disk for a swap area. Later i found out that it is pio4 and i want to relocate my swap area to sda.
Using GParted Live i am planning to create a swap partition to sda. Will fixing the entry in fstab be enough to correct this or do i need to do something more?
I could also use some advice on which live debian image i can install in sdc, to use for rescuing purposes. The capacity of the disk is 1080MB.
As a side note, the images i find for usd-hdd are direct download. Are there any torrent files for these?

I have an external 3.5" USB 250Gb HDD which is showing symptoms of hardware problems (repeated /var/log/messages errors of "reset high speed USB device using ehci_hcd"). This was originally plugged in to my NSLU2 running Debian Etch. I have just installed Ubuntu Desktop 9.10 to a spare Pentium-3M laptop and was hoping to copy the contents of this HDD to a fresh drive. However, I cannot mount it even read-only; mount -o ro /dev/sde3 /mnt/disk fails, and the /var/log/messages error is "recovery required on readonly filesystem", "write access unavailable, cannot proceed". I cannot understand why mounting a disk read-only should require write access. Following advice I googled elsewhere, I tried running mke2fs -n /dev/sde3 to try to list the alternative superblocks - but once again I got the error that the device was read-only. How can I go about accessing the data on this disk?

I have a problem trying to create an encrypted LUKS partition on a USB pen drive, but I don't know whether it is a hardware or software issue.
I just installed debian on this laptop with non-free packages:
Code: Select allroot@debianpc:~# uname -a
Linux debianpc 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) x86_64 GNU/Linux
Then just to learn cryptsetup I thought it was safer playing with a partition on an old usb pen drive. But when I try the command:
Code: Select allcryptsetup -v --debug --cipher aes-xts-plain64 --key-size 512 --hash sha512 --iter-time 3000 --use-urandom --verify-passphrase luksFormat /dev/sdb2
I get the usual message (Are you sure? ...), I type yes then it fails with code 22:
Code: Select all# cryptsetup 1.6.6 processing "cryptsetup -v --debug --cipher aes-xts-plain64 --key-size 512 --hash sha512 --iter-time 3000 --use-urandom --verify-passphrase luksFormat /dev/sdb2"
# Running command luksFormat.
# Locking memory.
# Installing SIGINT/SIGTERM handler.
# Unblocking interruption on signal.
WARNING!
========
This will overwrite data on /dev/sdb2 irrevocably.
Are you sure? (Type uppercase yes): yes
# Unlocking memory.
Command failed with code 22: Invalid argument
I had /var/log/messages open in tail on another terminal, but no message appeared. I tried the same command deleting one by one the parameters, but I got the same behaviour, so I don't think it is a parameter problem.

and I did a silly noobish thing. I have been using Ubuntu in various flavors for a little over a year now, and decided to install it alongside my Win7 Install on my desktop. Last week I read about BURG on omgubuntu.co.ukI am fairly certain I botched the install of burg somehowWhenever I turn on the computer, there is no display, not Mobo splash screen, not post, no GRUB menu nothing. the Display light is orange, indicating no input detected. But I know the OS is loading, I can hear it bootup, I can login, just by pressing enter, then typing my password, then enter again. Once I hear the login screen drum beat, if I turn off the monitor, then turn it on again, I get a super low res display. the driver works, compiz effects work, but everything is at 640 x 480. when I go to system-> preferences-> monitor the display is labeled as unknown and I can't change the resolution.I can access the BIOS, but the screen still does not detect the input, even if I power cycle the monitor after access the BIOS, so I won't try to change any settings, as I can't see what I am doing. The only reason I know I am in the Bios is that I can press f10 and then y to cause it to reset to default settings and cause a reboot.My system:ATi Radeon hd5870AMD Phenom II X4 3.4 GHzWD Velociraptor 300 Gb4 GbRamASUS M4A78-E

I purchased a new HD and my goal is to have a Windows partition, an Ubuntu partition, (a swap partition of course), and large fat32 partition for storing data to be used on both the Windows and the Ubuntu side.
I am installing from USB and do not yet have a copy of Windows to install. I keep getting an error saying that the attempt to mount vfat failed.

One of my disks in my computer crashed, it was the one containing /boot and some data partitions. The other system and /home partitions were on a second disk, which is ok.
I was wondering, can I create a new /boot partition, and keep on using the rest of the system? Can I somehow do it with a chroot from a live/installer disk, run grub, and use my system again? I have another disk which I can put in the system, but there is even an unused partition on the disk which is ok (but it is rather big for /boot).

In order to correct bug #459647 in compiz (as I have done on 2 other PCs) I downloaded, modified, and compiled the source with apt-src and make. Then I installed the produced .deb files with dpkg -i. For whatever reason the new compiz didn't have wobbly windows nor could I switch workspaces. Compiz is running and I do know however that compositing is working as Docky is still functional (and doesn't really work without compositing).
So I uninstalled all of the compiz packages and reinstalled the versions from the official repository. The same issue remained. During this time I have restarted my computer several times with different configurations. I tried to install compiz packages from the [URL]...ubuntu PPA and still the same problems exist. I'm not sure if there are any other problems that I haven't noticed yet. Finally, in an attempt to fully purge my computer of all things compiz and start over, I got the following error:
Code:
masen@dv6000m:~$ sudo apt-get autoremove --purge compiz*
[sudo] password for masen:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package compiz-code
masen@dv6000m:~$
I'm not sure what "compiz-code" is, but that's the name of the folder that I downloaded the source into. After this command, no packages are removed. I'm currently running Lucid 10.4.1 with all the latest updates. My graphics card is an Intel 945M mobile chipset. I run a similar configuration on 2 other computers with no issues. Has anyone ever seen this? Or have any idea how I can get compiz-code out of my package database. I know the problems I'm encountering aren't high priority, but not having workspaces gets annoying and I have no clue what else is broken with my 'half-broken' compiz.

I'm trying to create an extended partition. In GParted, I shrunk the size of the existing partition and now want to create a new EXTENDED partition in the free, unallocated space. GParted only lets me create a PRIMARY partition. What am I doing wrong here?
Here's what I've got right now:
You can actually ignore the flag for the swap as "boot." That was me just messing around trying to get it to work. I've removed that flag. Not sure how the question of boot affects all of this...maybe it factors in somehow.

I am a newbie to Linux and I am using CentOs. I am trying to create a new partion on my CentOs VM. I create a new primary partition using fdisk (I use the command fdisk /dev/hda). After I create the partition and use partprobe to write the partition to disk, I try to give the new partition a label. So, I use the command e2label /dev/hda LABEL=test
However, when I enter the command e2label /dev/hda3 , it doesn't display the label for the newly created partition. Am I doing something wrong here? Is the syntax of the e2label command wrong when creating the label for the new partition? Did I miss a step after writing the new partition to disk.

I downloaded the ISO from the Ubuntu site. I can run it from the CD without any problems however, when I install it, it freezes. I am installing on a 2nd hard drive in my computer. It gets up to the point of "Creating ext4 file system for / in partition #1 of SCSI1 (0,1,0)(sdb)... I've tried deleting the partition and creating one by myself with no prevail. I am going to school for computer networking and my counselor told me that it'd be a good idea to learn the Linux OS for my major.

I'm following the book RHCE book (5th edition) by Michael Jang. On the exercise on pg.140, creating partitions, I've created /boot (hda1), swap (hda2) and / (hda3). So far so good.
Next, I'm supposed to make an extended partition, containing the rest of the disk. So this should be hda4, right? But when I try to create either an LVM, or RAID partition, it creates hda4 AND hda5 under hda4. Why is that? Am I doing something wrong? The book next asks me to create /var as hda5, so if hda5 is already created automatically above, how am I supposed to create /var?

I have been using fedora 12 for last 6 months, recently I bought an external USB hard drive of 320 GB capacity. I made 2 partitions using the Disk Utility in Fedora. I encrypted the first partition as it was supposed to hold a lot of sensitive data, and yes it did have. Now I had to change my OS to AV linux for some audio-video editing work which wasnt being done properly on fedora due to some issue beyond my knowledge. now the problem is my encrypted partition is not accessible in my new installation. I see an empty space on my /dev/sda1. although no change to partition data has been done and the data on the second partition /dev/sda2 is easily accessible. when putting the drive on automount, is does not ask me for the password and neither does it show me the data. I have tried fdisk and sme other utilities but have failed to get my drive unencrypted.

I'm trying to set up a RAID1 partition on my Ubuntu 9.10 workstation.On this dual-boot system, Ubuntu is running from a separate drive (/dev/sdc - an SSD that is quite small, which is why I need more disk space). Besides that, there are two traditional 500 GB hard drives, which have Windows 7 installed (I want to keep the Windows installation intact), and about half of the space unallocated. This space is where I want to set up a single, large RAID1 partition for Linux.
(This, to my understanding, would be software RAID, whereas the Windows partitions are on hardware RAID - I hope this isn't a problem... Edit: See Peter's comment. I guess this shouldn't be a problem since I see both drives separately on Linux.)On both disks, /dev/sda and /dev/sdb, I created, using fdisk, identical new partitions of type "Linux raid autodetect" to fill up the unallocated space.
Device Boot Start End Blocks Id System
/dev/sda1 1 10 80293+ de Dell Utility
/dev/sda2 * 11 106 768000 7 HPFS/NTFS
[code]....
But so is "Device or resource busy" when trying to create the RAID array. Quite strange.
Update: Could the device mapper have something to do with this? How do /dev/mapper and dmraid relate to all this mdadm stuff anyway? Both provide software RAID, but.. differently? Sorry for my ignorance here. Under /dev/mapper/ there are some device files that, I think, somehow match the 3 Windows RAID partitions (sd{a,b}1 through sd{a,b}3). I don't know why there are four of these arrays though.
$ ls /dev/mapper/
control isw_dgjjcdcegc_ARRAY1 isw_dgjjcdcegc_ARRAY3
isw_dgjjcdcegc_ARRAY isw_dgjjcdcegc_ARRAY2

I have two hard drives in my desktop. One HD has a working Ubuntu system-hence the ability to post here- and the other contains Windows XP Pro. When the XP drive crashed I was able to re-install an image I had saved using Acronis. Unfortunately the dual-boot option at startup is no longer available. I can only boot to Ubuntu. Not so bad really but there are some programs on Windows that I need to use. Is there any way, using Grub perhaps, that I can reconfigure an MBR to include the second hard drive and the Windows system?

After realizing 10.04 Final doesn't support Intel 855 graphics card the hard way (upgrading to 10.04 from 9.10), I did some very silly things and now cannot even choose past kernals or go into failsafe graphics mode (which had worked prior to this).Long story short I screwed up GRUB. Because I am an amateur end user.I still have the 10.04 live cd. Can I reinstall this to put GRUB back to the original state?

I just installed kubuntu 10.10, replacing an older installation. I have three hard drives one of which had all of the data I wanted to save, about 500gb. I repartitioned and formatted the other two drives and made sure that the data drive would be mounted but not formatted. When I booted into my new installation, the data drive was blank. I'm not sure if it's relevant, but I had just upgraded the file system from ext2 to ext4 before starting the installation.
I've been trying to recover my lost partition with testdisk. The website has instructions for recovering a formatted partition. It looks like it's working until the instructions tell me to choose Boot and RebuildBS, which I don't see as options. Can anyone give me any advice on how to recover? How did this even happen? Has anyone had a similar issue with installation?

I recently accidentally corrupted my windows vista partition whilst trying to extend it via gparted under ubuntu 11.04 and then cancelling it shortly after starting. Resulting in me being unable to boot into vista (I don't have another copy of any windows OS so I'd really like not to have trashed this one )
Looking on gparted now my partition is Fat32(?) and apparently only has 36mb used =/

I recently suffered a hard disk failure, meaning I had to replace the faulty device. After attempting to mount the old faulty hard drive using and external caddy, I got the following message... Unable to mount 144 GB Filesystem Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb5, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
I'd like to attempt to recover what I can from my /home directory but unfortunately I use encryption (although I do actually know my pass phrase). What procedures and software can I use to try and recover data from this drive?

I had a tri boot of Win 7 /XP and Mint...I was using EasyBCD 2.0 as a boot manager...I booted Mint by configuring the NeoGrub option in Easy BCD..I wanted to uninstall Win 7 and so what I did was the following
1. Edited BCD bootloader settings ...Marked XP as my default and deleted Win 7 entry...
2. Logged out and wiped my Win 7 partition
With my fingers crossed , i rebooted but Easy BCD booted flawlessly with 2 choices XP and Mint(GRUB)...As Easy BCD is not meant for XP, I thought of restoring original NTLDR of XP so that things would be in place and thinking that this cud avoid problems of detection by other Linux OS I deleted manually the Easy BCD menu.lst file and NeoGrub.mbr in my root...That was it , after I rebooted, I got boot screen of EasyBCD but whichever option I select,I got an error message that address not Valid-NTLDR not found or something like that I booted my XP live CD and like many times before ran
1.Fixmbr
2.Fixboot
3.bootcfg /rebuild
After that , now when I reboot , I am getting "Invalid Partition Table" On booting from a linux CD , I can see the files are in place..I have to get boot sector and partition table fixed...

I've tried to resize my home partition using parted. Prior to it I had removed ext3 flags following some advices found on net. Resizing failed and I ended up with filesystem bigger than partition. Then I managed to enlarge the partition using fdisk but it didn't help. When I run fsck on it it prints:
