Stuck on boot screen, says preparing Automatic Repair

Try booting into your bios...
Google how to boot to bios (Manufacturer / Model number)
e,g How do I boot to bios on Dell Precision T3500
Try a hard drive test from there. Sounds like a hard drive error.
'preparing automatic repair' should end and give you options to troubleshoot if it isn't getting that far test hard drive.

use the operating system/install boot from it, then run repair the computer form the install menu

My next book is saying preparing automatic repair and then it says diagnosing your PC and then it starts all over what do I do

Hi

Run a chkdsk from the command prompt, once you have done this see if you can get on in safe mode and then restore it to a time before the update attempted to install

Hi, This is a problem in the BIOS my advice to you is get in touch straight away as you will always have problems! unless they are prepared to walk you through the settings in the BIOS. Be a happy PC owner & get this exchanged free of everything they should exchange the PC without any problems & they will pick up the present PC when they deliver the new one to you. I must add the blue screen is another problem with the Video card, Hence stick out for an exchanged PC it's their liability. Please leave me feed back: Malcolm Campbell, Thanks.

If it was me, I would get it warranty replaced. Even if you find a fix for this, it's going to hang over you like a cloud.

Okay provided the USB U created is bootable insert it first then restart and press the escape button. U should then come to a boot option screen if there is a + sign next to the hard drive option. expand it and choose the USB hard drive to boot from it ur files should start to load.

Hello there, i just owned a brand new Asus T100 for 2 days and today on the 3rd day after purchasing, i faced problems during boot/start up where the laptop gets frozen on the Asus logo screen.
I tried holding down the power button for 10 seconds and turned it on again. It ran a series of windows software updates before the start up, then after all software updates have been completed, the laptop resumed to freeze at the Asus logo screen again. I tried holding the power button for 10 secs followed by holding the power button and volume up button at the same time, to get into automatic repair/repair mode. THIS HELPS, get into the repair mode!

To cut it short, i tried the other advanced options as well as the restart button in the repair mode but to no avail. After carefully reading the different options in the 'advanced options' in repair mode...
Here's what worked for me:
1) If you're stuck at the Asus logo screen which doesn't seem to boot for ages or at least 10 minutes, hold down the power button for 10 seconds and let the screen turn black. (I did this with my charger plugged in, not too sure if it matters)
2) Count to 10 seconds. Switch the laptop on by HOLDING THE POWER BUTTON + VOLUME UP BUTTON at the same time. This will send the laptop into an 'automatic repair', followed by a 'diagnosing this PC' and after which you will see a blue screen which is the repair mode.
3) On the blue screen you will see 2 buttons, 'Restart' and 'Advanced Options'. Click on 'Advanced Options'. (DO NOT CLICK RESTART, it does nothing as you will get stuck again at the logo screen)
4) After clicking 'Advanced Options', click 'Advanced ....' (i forgot what exactly) and click 'STARTUP REPAIR'. This is the crucial part.Then follow whatever the system promts you.
5) Afterwards, it will attempt to repair your system then lead you back to the logo screen for startup.
6) Wait a few minutes and you should be able to get to your login screen as usual.

Hope this helps. I chanced upon it by guessing which would actually help me.

hi Andrew.
"Upon the 'Preparing automatic repair' window, press-and-hold Power button 3 times to forcefully shut down the machine. The system will enter boot repair page after 2-3 times of reboot, choose Troubleshoot, then go on to Refresh PC or Reset PC."
