    Can't boot into main drive after installing Windows on another drive


    Hi friends. I am a new member. Thanks for accepting me into the Forum. Yesterday, my HP G61 laptop's HDD finally crashed. I was getting unmountable boot volume error about a year ago, which I fixed by clean installing Win 10. It was ok till yesterday, when the system stopped booting. Error 301 and 303. Disk tests were ok till 56% then stopped. What I did, I removed the HDD in my Samsung netbook NC110 (which I was using sparingly), and installed it in the HP G61 laptop. The netbook was running on Win 10 32 bit. The HP was on Win 10 64 bit. I wanted to upgrade the system to 64 bit version, hence created a bootable media usb from Microsoft website. After installing the HDD in the HP laptop, I booted the system using the USB. The entire process went through, or that's what I guess happened. The system started working, with a little bit of tweaking with the display resolution. But, the Windows version remains to be 1803, whereas the previous version had the latest, the 32 bit version also stays. And, the USB has become part of the system. If I remove the USB, the windows doesn't boot. There is no option to "Eject" the USB. Apart form this, the system seems to be working fine. I have very limited usage of the laptop, checking mails, and online shopping. How do I bring the system back to normal working condition, and install the 64 bit version? Can someone please help me out?

    :)
     

  2. Windows 7 booting off wrong drive?!?!?

    Please move if this is in the wrong place.

    I have two hard drives, a 1.5TB drive, and a 160GB drive. Windows is installed on the 1.5TB drive, as are all my files and programs. The 160GB drive has a bunch of old files, and apparently the bootmgr and boot folder. Nothing else is on the 160GB drive, other than media files etc.

    If I remove the 160GB drive from the machine, windows refuses to boot, plug it back in, it works fine. The setup with two hard drives I have now is temporary, as the 160GB drive will go into another machine.

    My question is, can someone give me a step by step on how to make windows force to boot off the 1.5TB drive, ignoring the 160GB drive in the boot process completely?
    I don't know how to do this in Windows 7, on XP I would just run the /fixmbr command and its related ones.

    Any help would be appreciated.

    Note: I would really really rather not have to wipe and reinstall, I know it can be done without one as I've had this issue with XP before.

  3. Can't boot into main drive after installing Windows on another drive

    Installing Windows 7 via USB flash drive!

    Its weird tho cause I have no problem with installing from disc. I did change it back to boot from HDD. I really dont want to uninstall all my components, kinds defeats the purpose of installing from usb. it would take longer to disconnect and reconnect after install then it would to just install from dvd.

    Do you think its beacuse the drive was formated in ntfs, thats the only step I did different from the OP. Well that and the bootsect /nt60 command before coping files.

    heres they way I went, probly have to try it fat32

    launch diskpart.exe)
    select disk 1 (or your USB drive number, use list disk to get it)
    clean
    create partition primary
    select partition=1
    active
    format fs=ntfs
    assign
    exit

    Now that the drive is boot aware, we have to initialize its boot sector with the Windows boot manager (BOOTMGR), using the Bootsect.exe utility located in the boot directory of the Vista installation DVD. We have to tell the utility that our target drive is NTFS formatted:

    bootsect.exe /nt60 f:
