  1. Switch on your computer.
  2. Wait until the BIOS has finished loading, or has almost finished. (During this time you will probably see a logo of your computer manufacturer.)
  3. Quickly press and hold the Shift key, which will bring up the GNU GRUB menu. (If you see the Ubuntu logo, you've missed the point where you can enter the GRUB menu.)
  4. Select the line which starts with "Advanced options".
  5. Select the line ending with "(recovery mode)", probably the second line, something like: Ubuntu GNU/Linux, with Linux 3.8.0-26-generic (recovery mode)
  6. Press Return and your machine will begin the boot process.
  7. After a few moments, your workstation should display a menu with a number of options. One of the options (you may need to scroll down to the bottom of the list) will be "Drop to root shell prompt". Press Return with this option highlighted.
  8. The root partition is mounted read-only. To mount it read/write, enter the command
    mount -o remount,rw /
  9. If you have /home, /boot, /tmp, or any other mount point on a separate partition, you can mount them with the command
    mount --all (This must be done following step 8 so that /etc/mtab is writable.) Alternatively, you could try selecting "Enable networking" in step 7, though this has been found to cause the system to hang (see https://bugs.launchpad.net/ubuntu/+source/friendly-recovery/+bug/981792).
NOTE 1: If you have Ubuntu Quantal (12.10) or earlier, omit step 4 (the recovery mode menu items are displayed on the top-level menu).
NOTE 2: If you reboot, there is no need to hold the Shift key in step 3. The GNU GRUB menu will continue to be displayed automatically on each boot until a normal startup of Ubuntu completes. To configure GRUB so the menu is always displayed, even after a normal startup, see https://help.ubuntu.com/community/Grub2/Setup.

My acer aspire one has stucked on factory recovery mode, it has tucked when installing configuration for android on the 30/39


If you are installing an Android operating system on an Aspire One you will need to make sure you have a compatible ROM image. I would suggest you try and install a Linux OS such as Ubuntu or Mint. The Aspire One was available with Ubuntu from the factory.

After installing Ubuntu I logged out. Now is asks for a user name and passwork but I did't set any. I asked for it to automaticaly log on. How dos I fix it?


In Ubuntu 9.04 click on the main icon and select Restart.

- If Ubuntu is the only operating system on your computer you'll need to tap the ESC key as the system boots.

- If you have a
dual boot or multiple-boot system the menu should appear on its own.

- At the root level you'll get a boot menu. Select the one that says "recovery mode" and press Enter.

- Ubuntu continues to load until you reach the Recovery Menu.

- Arrow down to "

netroot

" which states Drop to root shell prompt with networking and press Enter.

- Now, at the root type "

password username

" (where username is the account whose password you want to change) and press Enter.

- You'll be prompted to

enter a new password

.

- You will not see the password or any evidence that you are typing.

- Retype the password. If both passwords match you'll have successfully reset your password.

- Press Enter to continue booting into Ubuntu.

hope it helps

I got a computer that has ubuntu 11.04/linux and it has a user name and password set but I can't figure out how to reset it.


When Ubuntu boots, select Esc for the boot menu (Grub) and select recovery mode. Ubuntu will then boot w/o asking you for a password signed in as root. Type passwd USERNAME and it will reset your password. source:http://in.answers.yahoo.com/question/index?qid=20110608030342AArlwua

I cant get the system to boot in any of the safe modes, widows will not boot or last known that worked will not boot. Is there something I could do in the setup utility to get it to boot in just safe mode...


If you are not concerned with your existing data, you can download tools from the HDD manufacturer that will allow you to wipe the drive quickly and easily.
If you are concerned with your data, you can attempt to use the F8 key during boot process to use advanced boot options within the Windows Recovery Environment (RE). If you cannot get the system to boot in this manner, try using your recovery media to boot the PC. This may require changing the boot order within your notebook's BIOS. A search engine should provide further assistance in performing this change and allowing you to use recovery media.
Should this fail, another alternative is to download a disc image of the Ubuntu Linux operating system and burn the image to a recordable disc or flash drive. Using the same steps you used for changing the boot order, change it to the media you've transferred the Ubuntu image to, and ensure it's inserted when starting the notebook.
Ubuntu should provide you a number of options to recover data, using the "Live CD" environment on the disc or the "Recover an OS in Trouble" option (the latter option may be paraphrased, depending on the version of OS you've placed on this media).

Follow the steps bellow:
1) Press escape key (or shift key) during ubuntu bootup proccess ultil you see de grub menu (if you have a dual boot you'll always see it).

Installed ubuntu 9.10 now can't boot XP. Black


Now that you have installed ubuntu which is linux did you make your pc able to do dual boot. It is possible you have overwriten some important files like master boot record while doing ubuntu installation. Most times blinking cursor means no hard drive or operating system. you can try poping in XP cd and try to do recovery if you have it. Also easiest would be if you could boot into safe mode and try to fix the issue by replacing missing or corrupt files.

Sansa Player - Unrecognized USB Device


alrigth it seems like you have formatted the recovery partition
if your sansa are working .. well if it´s starts then you should try
to go into recovery mode by having hold (on) and push rec button while starts the mp4 if it comes into recovery mode there then you can relese the rec button and connect the mp4 to the computer there you should see a device (15-16 mb ) in there it should be a file named : pp5022.mi4 you may try reset your sansa ( change the pp5022.mi4 file) you can download from http://chrisjs.com/PP5022.mi4

if you can´t come into reovery mode you got to do following
take it step by step and carefully read all twice before you starts:
you need to download ubuntu live cd learn more about that on www.ubuntu.com it´s is a open source os it´s free and anyone can change stuffs ect...
then burn ubuntu 7.10 to a cd or dvd
in the iso file i think after burning close the cd
and boot from the live cd with ubuntu so then when using ubuntu (you dont need to install it ) you do this :


There's four files you need to get, plus one you need to create. Copy and paste the following lines:
####
mkdir ~/e200t
cd ~/e200t
wget http://daniel.haxx.se/sansa/e200tool/e200tool
wget http://daniel.haxx.se/sansa/e200tool/i2c-e260.bin
wget http://daniel.haxx.se/sansa/e200/BL_SD_boardSupportSD.rom
wget http://chrisjs.com/PP5022.mi4
touch sansa.fmt
####

After everything finishes downloading, check the md5sum for each file:
####
md5sum *
####
That should return:

af26eb02fc3454f5264bb028107a2700 BL_SD_boardSupportSD.rom
d9f946067844e2a24fcbb6cfedb75057 PP5022.mi4
795cc4e75d38284a1460b840fc14967a e200tool
cecb257eeb64ceaae9cb20d9956a0bfc i2c-e260.bin
d41d8cd98f00b204e9800998ecf8427e sansa.fmt

If any of those lines don't match, redownload the file and check the md5sum again.

Then, make the e200tool file executable, switch to root (if you aren't already; enter password if needed), put your Sansa into Manufacturing mode, and program the i2c:
Keep in mind - there seems to be a 15 second timeout for Manu mode, so if you get a -71 error, try again.
####
chmod +x e200tool
sudo su
####
(Put sansa in Manu mode)
####
./e200tool init
./e200tool i2cprogram i2c-e260.bin
####
Also, you can use that i2c file even if you don't have an e260 - they're all the same.

I don't have a working Linux computer at the moment, but I believe at this point you need to turn your Sansa off. Hold power for 15 seconds, then go back to Manu mode.
Next, recover the bootloader to get to recovery mode:
####
./e200tool recover BL_SD_boardSupportSD.rom
####
When the display turns on, hold the REC button. If you don't get into recovery mode, try again.
Once in Recovery mode, place
i2c-e260.bin, BL_SD_boardSupportSD.rom, PP5022.mi4, and sansa.fmt
on the recovery mode drive.

Disconnect the sansa, turn off hold, and it should (hopefully) work. (chris did help me with this )
if you got any problems send a mail to skrap94@hotmail.com and write sansa e200 in top off message and try to say the problem if you got one let me know if you fix it it always fun :D
hopes this helps
