Ubuntu :: USB Boot Clears Data
May 13, 2010
my goal is to run Ubuntu from my USB as I go to lots of different computers. I would like to save files and settings to my USB each time I boot from a different computer. My USB is only 8GB but I figured it would be fine for what I am wanting to do.Anyway, when I boot into a computer, I am told that my USB only has 500mb of storage. That already irritated me. I decided to create a test word document. I save it to Documents and take out the USB. Once I am done, I boot into another computer. Not only are my background settings no longer in position, but that word document is not there.
Nothing gets saved at all to my USB. It isn't even letting me utilize my 8GB.Please help. I realize there are limits to booting from the USB, but a portable OS is the perfect solution for my circumstances.

It seems that something is causing the memory cache to be cleared when the screensaver launches. Then when moving the mouse or hitting a key to stop the screensaver it takes forever for the already launched and minimized applications to redisplay. I am using the ubuntu classic desktop.
Now time to rant.
Natty has so many bugs it is impossible to work around them all. This memory issue is one of the worst. The dead zone caused by the static application switcher, and the application switcher plugins for compiz (and probably any override redirect window) is another big one. There is not a single window decorator for compiz that works right. I have encountered two packages with binaries that won't even run (emerald and xpdf). The nvidia drivers seem to have issues (this may be related to this memory clearing issue).
Without a doubt more bugs than any other release of Ubuntu to date. I have worked around most of them by recompiling, and etc., but this is a real pain.
This is all aside from the idiotic switch to unity, when it is clearly not ready for release. The general direction of Ubuntu is really starting to look bad. By the way, what is up with the decision to uglify the desktop with gray scale icons (I know this is an old one, but I haven't really ranted on Ubuntu yet).
Looks like I will have to revert to Maverick.

I have Fedora 12 & GNOME. But, this actually is an issue with many Linux distro's and GNOME. If I set the Keep Aligned Check Box Off - the next reboot it is back too set on. (Right click empty area on GNOME Desktop). I have searched many forums and search engines, I must be doing my search wrong there must be others that have noticed this, And the posts I do find on it are sometimes pretty old, so it does not seem like a bug would be around so long. I saw some notes about Nautilus also but no answers. FYI In CentOS 5.4 & GNOME it works properly.

I'm having a minor inconvenient issue with Suse 11.2/KDE4.3.From a cold boot, and then the first login, the desktop and WM [Compiz-Emerald] loads ok, but the plasmoids/icons are not 'clickable', although I can use keyboard, Command Line and 'right click' menus ok.If I restart X, then log in again, everything is ok, and stays ok until the next cold boot.It's as if the plasma desktop is masked [if that makes sense?], but only on the first login, as if there is a boot sequence issue or something.

I have dual boot windows 7 and ubuntu 10.04. I had never booted to windows until yesterday by accident, and it did a massive update and hosed my ubuntu so it wouldn't boot. I have data that I'd like to get from my ubuntu partition before a reinstall. To make matters worse, I tried a grub change to try to fix the boot sector problems, and now it won't boot to windows either. It boots directly into the grub prompt. My question is, can I boot from a cd/usb and then access my hard disk ubuntu data so I can back it up over a network before I reinstall ubuntu?

I'm having an interesting issue with my computer right now. It has Ubuntu lucid installed, which was upgraded from karmic shortly after it became available and was up to date as of September 1.
The issue is as follows: It will not boot the internal hard drive (250GB Seagate barracuda). When I select any of the kernels, it appears to be booting, but 6 Hours later, no joy. If I select any of the Kernels in recovery mode, it does nothing, so again no joy.
It will boot my 500GB removable drive via USB (Samsung on the inside), which contains a backup of my lucid (cloned with Clonezilla) from June-ish, but will not do so if the internal hard drive is hooked up, so I cannot access the internals contents while using the backup USB HD.
Now this is where it get's interesting, at least for me. It will boot up a livecd while the internal HD is connected, which was the only way for me to access the contents of my Ubuntu partitions in the internal HD. I have since pulled the Internal out, removed the USB 500GB HD from it's case, installed it into the internal HD bay, hooked up all the cables, turned the computer on and it did boot. While it did seem to take a long while to boot, I'm hoping this may be because it needs a serious amount of updates (294 updates, 485MB are ready via synaptic!). So I now have placed the 250GB Seagate into the USB HD case and can now access it, but the only contents that can be seen, are the items in my defunct vista partition and I cannot find any remnants of my Ubuntu installation, despite gparted being able to see all of the partitions.

A friend's old Compaq Presario came with Windows XP. However, when it got buggy (without his knowledge or consent), his kids overwrote his OS by installing a warez edition of Windows 7 Ultimate. Unfortunately, that wiped out all his data, including photos of his late wife that he does not have backed up. I want to recover those if possible. I don't want to install anything because that may overwrite the photos if they're still there in some shape or form.
What I'm wondering is if there's a DVD-bootable distro of Linux specifically for data recovery. If I could boot to that, I could run its data recovery utilities without danger of putting anything on the hard drive. Once I've recovered the photos and backed them up to an external hard drive, I'm going to make his PC legal by installing Ubuntu. That's no problem. I'm very up to speed on that. What I need to learn is the best data recovery strategy via some type of bootable Linux. I suspect someone has written such a tool given how often people lose data due to viruses, accidental deletions, formats, etc.

I've been tinkering for over a week to try and get a functioning triple boot + shared data working. i've hit a road block. i'm using reFIt with SnowLeopard/W7/10.10. i can't get into ubuntu
*** Report for internal hard disk ***
Current GPT partition table:
# Start LBA End LBA Type
1 40 409639 EFI System (FAT)
2 409640 390772495 Mac OS X HFS+
3 391034640 781659639 Basic Data
[Code].....
OSX and Windows are fine. but whenever i select linux, it boots directly into windows. i'm hoping i don't need to install GRUB2 to the windows partition as that would defeat the purpose of reFIt (would it not?)

My Lucid LTS Ubuntu Studio 64 (amd) won't boot anymore; / and /home each are software raid 0 partitions.
I have a Multimedia partition (also ext 4) which I attempted to chmod with a GUI program (I forget what its called now) to enable all users read/write access. Looks like I inadvertantly fstabed that partition to be mounted at boot-time (normally my password was required in order to mount it).
I tried to logging out and back into my OS to see if the partition was now writable but it wasen't; instead a filesystem error was noted. I realised then that my partition was IMPROPERLY labelled and I was in a tired state and didn't remember how to rename it & rebooted to make sure all was ok. But it was not:
An error occured when mounting /media/Ubuntu unknown filesystem type "Multimedia"
mountall: mount /media/Ubuntu [1334] terminated with status 32
mountall: filesystem could not be mounted /media/Ubuntu
Boot: recovering journal
From my generic Ubuntu system on a non raid partition, I finally removed the space in the 'offending' partition: Ubuntu Multimedia to UbuntuMultimedia. And I changed the permissions for it. But if I try to boot Ubuntu Studio via recovery; booting in low res is unusable, and it gets stuck if I SKIP mounting. So I am left with manual boot or drop to a shell. I will have to use an editor like vi or nano and the command prompt. I know that I likely only have to comment out a line in /etc/fstab but I am only familiar with nautilus or gedit for this type of operation. And since this OS is on a raid partition its not 'seen' on the live CD..I would need someone to offer me clear steps to follow with the non gui editors otherwise I'm in trouble... I just wanted to use that partition for video editing and now I am locked out of my system!

I had issues on my last install , I couldn't boot into it cause I accidentally uninstalled python 2.6 and everything it was attached to. So I reinstalled on a separate hard drive, I can see my other file system from the media folder but the only thing in my home dir is these 2 files 1 read me that says
PHP Code:

From the graphical desktop, click on:

But when I click it and try to run it I get this error

Generally I am used to installations of dual boot on different partitions(the traditional method) any windows OS with any ubuntu OS.I tried that with backtrack 4 and Ubuntu 10.04 netbook edition! I had previously installed ubuntu 10.04 and then had an extra partition that had data in it.Went ahead to boot with the backtrack 4 disk BUT it did not give me an option for installing them side-by side so i did it manually by editing the partition with the partitioner! I had 2 swamp spaces one i which was initially there for Ubuntu and the other i created! Then simply formated ine partition with EXT3 and mountpoint of / which made two of them!after installation, the grub shows that there is another OS but when it does not load!

when I installed Ubuntu 9.10 I put in one time setting but it was wrong, and now I don't know where to change it. I tried to change the time preferences, but on reboot I am back to the wrong time.
I know the data is in there somewhere and I can change if I knew where it was.

Personnally up until now I've been using either NTFS or a ext3 fs driver from Windows. I wonder if there's a better way. Probably NAS is the best, but not really practical with a laptop.

I am installing a custom 8.04 live disk (basically, a mirror of my whole system with user data intact, sans all non-OS files) from a USB key with remastersys for the .iso creation, and UNetbootin for the bootable USB on a brand new 120GB PATA WD HDD. Both do nicely so far, so I have a working livedisk to use until I need to install Ubuntu to the drive.
I had a pure linux box, but I need to add XP with dual booting now- I have to use Autodesk Inventor 2010 software for my college class on my laptop, so I don't drive 30 miles to use the 1 computer lab equipped with that software. I'm not new to Linux, but I am new to more in-depth partitioning. I've taken the lead and looked into things- read this good guide, among others:
HTML Code:
http://www.psychocats.net/ubuntu/partitioning and noticed that there is a way to more deftly use partitions so that personal files can be shared access and write between Windows and Linux partitions- with this:
HTML Code:
http://www.fs-driver.org/ Ubuntu is still my main OS, but being able to access all my media/data files between the 2 systems would be nice. Problem is, until now, I've put everything on a single partition because I didn't know better. Now I do, but am a bit confused with all the guides as to what's most efficient, especially in my case where full RAM speed is crucial to running a single program.
Here's what I know I need to do: 1. The Windows XP install I know needs from 20-30GB for Inventor 2010 LT to work well. I don't need anything else in XP spacewise- it's just being added for Inventor. 2. I'd like to create a separate /home partition for Ubuntu this time to save my user data, making future upgrades much more painless (I will be getting Lucid soon). How that works when upgrading, though, I don't know yet..
3. I'd like both OSes to share all my personal files (docs, pics, music, Inventor design files) if it is an efficient choice that works without problems.
4. Finally, because 2GB is minimum for Inventor to run decently, I need to maximize the speed of my RAM for it- from my reading, these so-called "swap" partitions can somehow be added for buffering this- people seem to sugguest the swap be half the size of the RAM for fastest speed, and some say add separate /usr or other partitions. I'm not clear on what would be most efficient for me.
I have limited HDD space- because of my laptop's BIOS, this single 120GB drive is the biggest I can get on my laptop, so efficient partitioning would make a huge difference for me. Before this, a 60GB HDD was in this. I'd like to see some added space for my data storage, but still keep things as fast as possible for Inventor when I use it, and Ubuntu.

I'd like the final layout to have a Windows partition (will start out as XP and will become Win7 when I can afford yet another copy), a partition for Ubuntu, and a shared Data partition that I can use for all my files between both OSs. I think this should be fairly straight forward with Linux on a Primary partition with / and swap. Only thing is, from what I've read (and yes I know this is a bit old school) it might be a good idea to put in a /Home partition so that I can reinstall new upgrades and maintain settings. But I don't want to max out my 4 primary partitions so I can use a 4th partition as a kind of sandbox for OS testing without using VirtualBox all the time.
This leaves me in need of some advice, I've never used Fdisk and I was planning on just using the Ubuntu installer to do all of this, but I don't know if I can create /Home as a logical partition in the main Ubuntu partition and still have the benefit of being able to reformat /root without losing /Home. I might have just confused myself, because no matter how many guides and How Tos I read I still don't really get extended partitions, I understand logical vs. primary but extended is...confusing. I need the Ubuntu partition to be bootable, so it needs to be a primary partition...I think. Unless I can have: /boot, /, swap, and /Home...
Also, if Ubuntu can read NTFS, and Win7 can read Ext3, what should a do with /Data? Or should I just go with FAT32 and be done with it. (It's a big HDD btw, 640 GB, so /Data will be fairly large)

how to set up a boot partition on the first hard drive separate from two RAID 5 configurations on a Supermicro server with 1-750GB hard drive for the boot partition, and 15-1TB hard drives for data. The 15 hard drives are split into two RAID 5 configurations (7 -TB drives and 8 1-TB drives). I will be installing CentOS 5.2, and the 15 Terabytes of data will store data, and the 750GB hard drive(on port 0) will only have the 100MB boot file. I am using 3ware BIOS Manager to configure the first array of 7 hard drives, and the second array of 8 hard drives (1 drive with boot information will not be included in the array).
to recap, picture this: I want to load CentOS on this server. /dev/sda1 (on the bottom left drive) needs to house the boot partition set for 100MB. The remaining 7 drives (the left half, not counting the boot drive) need to be set up as a RAID 5 array. The eight drives on the right (right half) also need to be setup as a RAID 5 array. After I configure this in BIOS, I run the CentOS setup disk in graphical mode. I get to the portion after the Language and keyboard setup where it says "Installation requires partitioning of your hard drive. By default, a partitoning layout is chosen which is reasonable for most users. You can either choose to use this or create your own. Select the drive(s) to use for this installation". The drives listed are:
"sda 5721980 MB AMCC 9650-SE-8LP DISK"
"sdb 1020 MB AMCC 9650-SE-8LP DISK"
"sdc 714218 MB AMCC 9650-SE-8LP DISK"
"sdd" 6675643 MB AMCC 9650-SE-8LP DISK"
When I choose "Remove Linux partitions on the selected drives and create default layout." or any other option, I get different errors. I notice when configuring via text mode I get better options to install. I can't install the boot drive separate from the two RAID configurations?

I have a Windows laptop that isn't booting up anymore for some reason Safe Mode doesn't even work. Looking at what is printed out when it hangs, I did a search on google and it is some sort of HP laptop problem. Apparently the hard drive should still be OK, if only I can access it somehow. I was thinking maybe I could use one of those live Linux CDs to boot up. But I'm not too familiar with those. Would they be able to detect the laptop's DVD burner, and allow me to burn files off the NTFS partition to a blank DVD? I want to get my data off before I hand the laptop over to the IT department - who knows what they will do to it. So exactly which live Linux CD flavor should I use (my other working computer only has a CD burner)? And then would it be easy to burn a DVD after booting up the live Linux CD?

I've been using Excel from OpenOffice with moderate success for the last year. Now I've just tried to open a new spreadsheet and I'm suddenly getting a highly condensed view. The cells are about 1mm X 4mm. If I expand them by selecting and dragging, then try to copy data from another spreadsheet onto the new one, the data shrinks to the small scale -- unreadable.
