So many probs. Not starting W7: BootMgr is Missing | No Bootable Devic

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!

:welcome:    Politics,

 

First thing that I suggest you do is to try and back up your data and second test the HDD to see if it has issues, the former needs to be done first as testing a flaky HDD can cause it to fail completely with the loss of all data on it, will post the testing info after the data recovery has been tried;

 

=================== 

***Required Hardware*** 

CD Burner (CDRW) Drive, 

Blank CD, 

Extra Storage Device (USB Flash Drive, External Hard Drive)  

=================== 

 

1. Save these files to your Desktop/Burn Your Live CD:

  • Download Latest Puppy Linux ISO (i.e.: lupu-528.iso) 

    Download BurnCDCC ISO Burning Software 

     

    There are instructions on how to boot from flash drive with puppy here; / 

     

    For computers that have UEFI as opposed to legacy BIOS, to be able to boot from your USB device you may need to disable secure boot and change UEFI to CSM Boot, not all computers and BIOS are the same, please refer to your user manual if you have one as the following steps are only one such example.

     

    Restart the computer, Windows 8 and 8.1 from the Start or desktop screen move your mouse pointer over the upper or lower right corner of the screen, when the Windows Charms appear click the Settings Charm, click on Power and then the Restart option.

     

    Windows 10, Click on Start,Power and then Restart.

     

    While the computer is re-starting,you will need to continually tap or hold down the particular key that will allow you to access the BIOS on your computer, we will use the F2 key as an example here;

     

    After restarting the computer, when the screen goes black, press and hold down the F2 key, wait for the BIOS to load.

     

    Select Security -> Secure Boot and then Disabled.

    Select Advanced -> System Configuration and then Boot Mode.

    Change UEFI Boot to CSM Boot.

    Save the changes and Exit the BIOS, commonly F10.

     

    If your computer will not boot into Windows at all, power up or restart the computer continually tap or hold down the key that will allow you to access the BIOS on your computer and then do the following;

     

    Select Security -> Secure Boot and then Disabled.

    Select Advanced -> System Configuration and then Boot Mode.

    Change UEFI Boot to CSM Boot.

    Save the changes and Exit the BIOS, commonly F10.

     

     

  • Open BurnCDCC with Windows Explorer 

  • Extract All files to a location you can remember 

  • Double Click 1%20BurnCDCC%20Icon.PNG BurnCDCC 

  • Click Browse 2%20BurnCDCC%20Browse%20Button.PNG and navigate to the Puppy Linux ISO file you just downloaded 

  • Open/Double Click that file 

    IMPORTANT: Adjust the speed bar to CD: 4x DVD: 1x 

  • Click Start 3%20BurnCDCC%20Start%20Button.PNG 

  • Your CD Burner Tray will open automatically 

  • Insert a blank CD and close the tray 

  • Click OK 

Puppy Linux Live CD will now be created 

 

2. Set your boot priority in the BIOS to CD-ROM first, Hard Drive Second 

  •  

  • Start the computer/press the power button 

  • Immediately start tapping the appropriate key to enter the BIOS, aka "Setup" 

    (Usually shown during the "Dell" screen, or "Gateway" Screen) 

  • Once in the BIOS, under Advanced BIOS Options change boot priority to: 

    CD-ROM 1st, Hard Drive 2nd 

  • Open your ROM drive and insert the disk 

  • Press F10 to save and exit 

  • Agree with "Y" to continue 

  • Your computer will restart and boot from the Puppy Linux Live CD

3.  Recover Your Data 

  • Once Puppy Linux has loaded, it is actually running in your computer's Memory (RAM).  You will see a fully functioning Graphical User Interface similar to what you normally call "your computer".  Internet access may or may not be available depending on your machine, so it is recommended you print these instructions before beginning.  Also, double clicking is not needed in Puppy.  To expand, or open folders/icons, just click once.  Puppy is very light on resources, so you will quickly notice it is much speedier than you are used to.  This is normal.  Ready?  Let's get started. 

     

    3a. Mount Drives[list] 

  • Click the Mount Icon located at the top left of your desktop. 5%20Puppy%20Linux%20Mount%20Icon.PNG 

  • A Window will open.  By default, the "drive" tab will be forward/highlighted.  Click on Mount for your hard drive. 

  • Assuming you only have one hard drive and/or partition, there may be only one selection to mount. 

  • USB Flash Drives usually automatically mount upon boot, but click the "usbdrv" tab and make sure it is mounted. 

  • If using an external hard drive for the data recovery, do this under the "drive" tab.  Mount it now. 

 

3b. Transfer Files.

  •  

  • At the bottom left of your desktop a list of all hard drives/partitions, USB Drives, and Optical Drives are listed with a familiar looking hard drive icon. 

  • Open your old hard drive i.e. sda1 

  • Next, open your USB Flash Drive or External Drive. i.e. sdc or sdb1 

  • If you open the wrong drive, simply X out at the top right corner of the window that opens. (Just like in Windows) 

  • From your old hard drive, drag and drop whatever files/folders you wish to transfer to your USB Drive's Window. 

 

For The Novice:  The common path to your pictures, music, video, and documents folders for XP is: Documents and Settings >> All Users (or each individual name of each user, for Vista and above  C:\Users\$USERNAME\[...]. CHECK All Names!) >> Documents >> You will now see My Music, My Pictures, and My Videos

 

Remember to only click once!  No double clicking!  Once you drag and drop your first folder, you will notice a small menu will appear giving you the option to move or copy.  Choose COPY each time you drag and drop. 

 

YOU ARE DONE!!!  Simply click Menu >> Mouse Over Shutdown >> Reboot/Turn Off Computer.  Be sure to plug your USB Drive into another working windows machine to verify all data is there and transferred without corruption. Congratulations!

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?

What is ASCI method?
Disconnect all attached devices including all internally attached hard disk drives and see if computer boot pass Acer Boot screen.
