Booting Linux From A Flash Drive For File Recovery

admin — Sun, 24 Oct 2010 03:37:58 +0000

We are here? to talk about some interesting things that can be technology? to? do with a USB flash drive. Today’s topic be? focuses on the Linux operating system boot from a USB memory. The goal to boot Linux from a USB drive, at least prop? Site of this guide? To? to recover files from a broken install the Windows operating system or any other OS for that matter. Tambi?, You can run virus distribution? N Linux safely without infecting other computer or having to boot the infected PC.

? Qu? necessary:

* A USB flash drive anywhere from 512 MB to 2 GB (depending on the distro) * A motherboard can boot from a USB device. * And about 15 minutes m? S? Download time.

Software:

* La? Last version? N Stable UNetbootin

Step 1: Prepare the unit? USB

Once you have all the supplies to pull together and connect the USB drive and backup all files stored on your disk.

Step 2: Install the USB port

UNetbootin implementation and select the following:

1. Use the first button? N “implement.” This download? and the installer? autom? cally, the distribution? n you want. 2. Choose SystemRescueCd. We’re going with this because? ? F? Easy NTFS file system driver to avoid mixing of customization? No additional? required. 3. A continuation? N, select your flash drive. NOTE: coldness, select the unit? flash and not participate? No Windows or participation? No primary, because if it does, then destroy? currently installed operating system. 4. By? Finally, click “OK.”

UNetbootin to select the options shown in the image source located at the link at the bottom of this article? Ass.

Step 3: Configuration? No BIOS

We will have to configure the unit from USB memory. To this end, the mother will have? the first tab? support this functionality? and the second be? to do some “config? n.

1. Restart the computer and press “F2? O”, depending on the motherboard to enter the BIOS configuration? N. 2. Look for the section? N called the boot sequence, or denomination? N the same way. This sometimes stored in a section? n separately as Advanced BIOS Features, or the like. 3. Move strange USB ble or the top of the list. If you do not see these options in the list, m? s likely your motherboard does not support USB boot. check Google for m? s information? No respect. 4. Restart your computer with the drive plugged in

Step 4: From Linux

Let’s start with the l? Command line of this guide? A. There are options to load an interface gr? Chart for those who tremble at the CLI. I have to warm even though the S-command line? much more? s? r? request and f? cyl.

1. Once the team enters the post can? S see the bootloader screen. Go to “VMLinuz64″ and press enter.

Next? S of a series of goods and m? S likely in the display, not red? system “root @ ra? sysresccd z /%.” This show? To? Success.

Step 5: Copying files from a partition? No Windows on an external hard drive.

To do this, you will need? outside help to move files that are ready to receive data. ? Tambi? N can use the USB stick? was started of course, if c ‘? enough space in it.

1. First you? need to identify our unity?. Suppose you have two storage devices connected in a single flash unit and the other windows on the hard disk. Run the following command:

fdisk-l | less

This command will show? all storage devices in the system. Use the arrow up and down? to navigate through the exit as you can? be m? s? much of the screen. My output from this command? as follows:

Disk / dev / sda: 160. 0 GB, 160 billion bytes

255 heads, 63 sectors / track, 19452 cylinders

Unity? = Cylinders of 16065 * 512 = 8225280 bytes

Disk ID: 0xd0f4738c

Device Boot Start End Blocks Id System

/ Dev/sda1 * 1 19451 156240126 7 HPFS / NTFS

Disk / dev / sdb: 2085 MB, 2085617.664000 bytes

2 heads, 63 sectors / track, 32329 cylinders

Unity? = Cylinders of 126 * 512 = 64,512 bytes

Disk ID: 0x00502bcd

Device Boot Start End Blocks Id System

/ Dev/sdb1 * 1 32330 2036720 6 FAT16

The device? 160 GB participate? N NTFS. Know the two bits of information? No you can? have a hip? thesis and say / dev / sda? our Windows devices.

NOTE: To exit this screen, press “q”.

2. Windows install disc so you can access the files in? L. Run the mount command to continuation? N:

mount / dev / sda / mnt / windows

NOTE:? need to replace “/ dev / sda” with the device in the output of fdisk-l. E ‘probable? which are the same.

3. Let’s see if we put the device right now. Run:

ls / mnt / windows

This command lists? files and folders in a directory. If you see the tell tale Program Files directory and Windows? installed correctly.

4. Out for our backup device. Plug it in and wait a few seconds and then run the fdisk command again:

fdisk-l

or

cat / proc / partitions

You should see the two devices you have seen? Last time and now duty? be the new?. Match the size or your device and enter the location? N of the m? S probably / dev / sdc.

Connect this device to the backup folder pre-made with the mount command again:

mount / dev / sdb / mnt / backup

5. Now? time to copy things from the old disk to disk backup for Windows.

To copy the entire disk to disk backup for Windows to run the following command:

cp-R / mnt / windows / / * / mnt backup / YOUR_FOLDER_NAME

If you think of a single copy of the file type the full path and continuation? No full destination path.

Learn m? S control? ? Useful:

* Sometimes, a virus has infected the first bit of c? Say your system is running in the MBR (Master Boot Record). Fortunately, we can clean it with relative ease? in linux. Run:

dd if=/dev/zero of=/dev/sdb bs=512 count=1

Remember to replace “/ dev / sdb” with the device and clean, because if you miss the evil that you may have some problems.

* Maybe you do not have an external device to do things, but have another computer with a network share. Well we’re going to mount a network share to copy files? L. Create a mount point:

mkdir / mnt / network

Place components:

mount-t smbfs / / computername / folder / mnt / network name-o = user1, password? a = mypasshere

Now? can copy and move files on the network share as any other directory.

To mount a share without using password? As:

mount-t smbfs / / computername / folder / mnt / network

To pr? Maximum.

3. 5 Newsgroups

blogging, blogger,blogspot,make money from blog

Despite their drawbacks, newsgroups can be a very efficient way of finding the information you need.

Before going to the newsgroups, I would highly recommend the Google news archives (http://groups. google. com , once known as DejaNews). This is a huge archive of newsgroup postings and you can search it using nice search tools. This way, you can often find an answer to your question without going through tons of trash, and without exposing yourself to anger after posting a question which “was already asked ten times this week”. You may be surprised by the amount of information available through the google archive.

There are several newsgroups devoted to Linux and they seem much better than other newsgroups (maybe they are better policed by the Linux experts?). Here is a short list:

news:comp. os. linux. announce (moderated–the postings are done by a moderator, who reviews them prior to the posting. Inspect the footer of any message for info on how to post. )

news:comp. os. linux. setup

news:comp. os. linux. hardware

news:comp. os. linux. security

news:comp. os. linux. misc (miscellaneous)

news:comp. os. linux. advocacy (Use this one for discussion of pros and cons of Linux and perhaps a comparison of Linux with other operating systems. This is an excellent newsgroup if you like getting into endless arguments).

news:alt. linux. sux (Here you can read/write really all opinions on Linux. )

news:comp. os. linux. networking

news:comp. os. linux. x (X-windows)

news:comp. os. unix (general UNIX newsgroup)

Please note that there is a newsgroup etiquette (“netiquette”), and you risk rejection and perhaps expose yourself to flames if you choose to break it. The major points:

Don’t post on a topic that is unrelated to the subject of the newsgroup;

Don’t post to many newsgroups at the same time (cross-post) ;

Use plain ASCII, don’t post attachments, pictures, html, etc. ;

Don’t advertise (particularly commercial products) ;

Don’t write UPPER CASE ONLY – THAT GETS YOU KILL FILED.

Use a simple descriptive subject (“HELP” isn’t going to work) and briefly explain your problem. Include distribution and version number, and identify the hardware (USR 56K modem is wrong – list the model number).

To read newsgroups (also called usenet), you have to configure your access to a newsserver. The simplest may be to use mozilla (“edit”-”preferences”-”mail and newsgroups”) and specifying the news server (your Internet Service Provider, ISP, should have given the name of the server) and then add the appropriate newsgroup to your list of local “mailboxes”. If you don’t know the name of the news server, try: “news. my_isp_provider_name. and_domain”, or perhaps just “my_isp_provider_name. and_domain”.

For news reading, I prefer knode& (type in the X terminal). Installation and learning newsgroups was certainly worth my effort.
