My Acer netbook 8.9" is not booting up. It's stuck in a loop. Looks like it's in a doss screen where it is asking me to choose between starting windows normally, safe mode with networking, safe mode with command prompt and last know configuration of the most recent setting network. I tried to use each of them but nothing works. stuck in the same loop.

it could be a problem with hard drive, try replacing it with a spare hd , if its still the same then maybe you could take out internal battery and put it back in ,even take out mem and put back in at same time of taking out internal battery ,it could help resolving the problems.

Hi,
try pressing the power button and holding it for 10 seconds. Then wait a while. Turn it back on, you may press F12 or other key when the Samsung Logo appears (before Windows Logo) to see the boot options. Choose the one to check for any errors or anything else - Run diagnostics. Then also you may scan your hard drive for any failures.

Go to "Start" > "Restart" to reboot your netbook. Hold down "Alt" and "F10" when you see the Acer logo on the screen. The recovery menu will load. Hit "Enter" and then "Next" to see your recovery options. Choose "Factory Restore" to set your netbook back to factory settings. Follow the instructions on the screen. Choose your time zone and language when the customization menu appears. Reboot the netbook when you are prompted. Restore your saved files from the flash drive. or Click on the Start menu.

When the eRecovery menu appears, choose "restore system to factory defaults". Wait for the recovery process to complete and the computer to restart Hope this helps.

At boot do you get the Acer logo or can you enter the BIOS or the restore/recovery with the F keys?

When you get to the options screen, press safe mode.
Let it boot completely into safe mode.
Then do a normal restart. Should work

Hi,

Have you tried to press F8 when the system boots ( initial screen ) and tried the safe mode or last known good configuration ?

If this does not help, try a recovery disk and it should work.

This recovery process helps you restore the C: drive with the original software
content that is installed when you purchase your notebook. Follow the steps
below to rebuild your C: drive. (Your C: drive will be reformatted and all data
will be erased.) It is important to back up all data files before using this option.
Before performing a restore operation, please check the BIOS settings.
1 Check to see if Acer disk-to-disk recovery is enabled or not.
2 Make sure the D2D Recovery setting in Main is Enabled.
3 Exit the BIOS utility and save changes. The system will reboot.
Note: To activate the BIOS utility, press <F2> during POST.
To start the recovery process:
1 Restart the system.
2 While the Acer logo is showing, press <Alt> + <F10> at the same time to
enter the recovery process.
3 Refer to the onscreen instructions to perform system recovery.

Try tapping F8 when the acer window shows, when it shows the muliboot option, scroll down to "Last Known Good Configuration" and hit enter. If it does not boot normally, you will have to get an external dvd drive and boot off the drive with a windows installation disc to perform a repair.

You have a corrupt Windows system configuration/registry. Someone else chime in if there is hope, but my only solution (given it won't start up in safe mode) is to wipe and reinstall.
