Long story short, Acer Laptop Win 7 Home Prem. X64 was working fine & then I dropped it five feet from the ground. Then when I started it hung on the Win 7 Logo. Then I inserted the reinstall USB & entered command prompts & now it's not even displaying a logo. I'm assuming something in the hard disc got partially damaged.

 

There are 2 scenarios.

 

1] When I go to BIOS and leave the hard drive on AHCI mode & try to start up, I get the 'No bootable device -- insert boot disk & press enter' error.

 

2] When I go to BIOS and the hard drive on IDE mode & try to start up, I get the 'BootMgr is missing press any key to restart' error.

 

 

 

BIOS detects hard drive. EaseUS partition manager detects the drive but can't recover any boot partitions.

 

 

I already tried the Startup Repair many times over, no luck.

 

 

Here are some of the commands I entered in to the command prompt from the reinstall disc and still no luck. 


bootrec /FixMbr
bootrec /FixBoot 
bootrec /RebuildBcd
chkdsk /f C:
chkdsk /r C: 
chkdsk 

Also did these :

Command #1 – diskpart
Command #2 – list disk
Command #3 – select disk X
Command #4 – list partition
Command #5 – select partition 2
Command #6 – active
Command #7 – exit

And tried these but ran into errors on one of these steps I believe so I didn't complete the steps...

bcdedit /export C:\BCD_Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /RebuildBcd

Nothing worked. Hard Drive is a Hitachi HTS545050B9A300 . I haven't formatted the disc as I have important files on there,

 

Any little bit of help is appreciated. Thanks!

Here's some repair/recovery/restore options (in this order):

 

1 - Startup Repair.  Run it 3 times, rebooting in between tries.

2 - System Restore to a point before this started happening.

3 - DISM/SFC repair (DISM doesn't work with W7, although SFC does)  - look below at the next Quote box for instructions on how to do this from Startup Repair
    

 

Then please run the following DISM commands to see if there's any problems with the system (from an elevated (Run as administrator) Command Prompt).  Press Enter after typing it:
   
Dism /Online /Cleanup-Image /RestoreHealth
    FYI - I have repaired systems using the last command even though problems weren't found with the first 2 - so I suggest running them all.

    From this article: http://technet.microsoft.com/en-us/library/hh824869.aspx

    You can also run sfc.exe /scannow from an elevated (Run as administrator) Command Prompt to check for further corruption. Include the CBS log (located at C:\Windows\Logs\CBS\CBS.log) if you'd like to have a Windows Update expert check it (I don't check them because I can't read them)


4 - RESET using the "Keep My Files" option (W8 calls this a REFRESH; W7 and earlier doesn't have this function)

5 - Repair install of the OS (Thanks to FreeBooter!):

    "Non-destructive reinstall of Windows XP"

6 - RESET using the "Remove Everything" option (W8 calls this a RESET; W7 and earlier doesn't have this function)

If using W7 or earlier, this can be accomplished by resetting the system by use of the recovery partition/recovery disks/recovery drive.
If you don't have them, you can usually order them from the OEM manufacturer of your system ( US points of contact here:  http://www.carrona.org/recdisc.html )

7 - Wipe and reinstall from the Recovery Partition (if so equipped)

8 - Wipe and reinstall from Recovery Media - to include deleting all partitions.
If you don't have them, you can usually order them from the OEM manufacturer of your system ( US points of contact here:  http://www.carrona.org/recdisc.html )

 

Here's the DISM when you can't boot to Windows:

 

DISM /Online should only be used when running from within Windows. Run this command instead:

Dism /Image:C:\ /Cleanup-Image /RestoreHealth
Did you also try doing SFC scan while booting off of Recovery Environment or Install Disk? In those cases, the commands are slightly different:
sfc.exe /scannow /offbootdir=c:\ /offwindir=c:\windows

Fast forward a couple of months and here's the update. I totally F'ed up! I was able to install Win 7 via IDE after forcefully & unwillingly having to format the drive and then I tried to install via the other ASCI method I think and then I don't know what happened.

 

 

 

Now I have a laptop that won't go past my Acer Boot screen. It just stays on the Boot screen. It won't even respond to my F2 or F12 clicks. Nothing works. It's just a frozen screen as soon as I turn it on and just stays there. Is there any hope for this or is it salvage?

This seems to be beyond my abilities here.

I'd suggest posting over in the Internal Hardware forums for some more expert advice:    http://www.bleepingcomputer.com/forums/f/7/internal-hardware/
