    Hello, I have a problem with the computer, and after using the programs and turning them off, I cannot run another one. I decided to reinstall the wines 7.
    I have win7 in the .iso image
    I made a bootable flash drive with rufus

    And here the next problem begins, because by changing the first boot devices in bios, I set this USB and then my drive with the current win.
    But it still runs win from disk, not the installer from pendrive.


    I will add some information
    8gb flash drive
    Gigabyte motherboard - GA-A75M-D2H

    Maybe some of you know the answer what to do to run the installer from this usb?

    Disconnect the HDD and check if the flash drive boots at all.
    Are you able to connect your HDD to another computer?

    A message (system installer) will appear and it should run until it says that there is no HDD or no space to install the system. Thanks to this, you will be sure that the flash drive has been properly prepared.

    Do you have any other partitions (files) on your HDD that you need to keep?

    You still have a badly configured BIOS.
    You did not read everything from the link of post no. 2 or you have not made all the changes to the BIOS.

    It's best to show all possible BIOS tabs (screenshots), maybe we'll see the gaps on them.

    OK - it's not even a UEFI bios.
    Connect the flash drive to USB 2.0 (not 3.0).
    Check without disks if it boots. If not, it was badly prepared.

    What other computer do you have to prepare the flash drive (PC, laptop, what operating system on it)?

    After disconnecting the disks, you only see this inscription
    "Loading operating system" (comes on usb 2.0 port)
    And nothing else happens :)
    It is possible that it is badly prepared, I do it 1 time, but all of the instructions from the link from the 2nd post, the rufus program

    I want to install win 7 HP

    Unfortunately, I do not have another to check, but the current one is still win 7. So I can work to repair this pendrive

    Make a pen again by selecting mbr / bios and uefi from the drop-down list 1.

    We go with the appropriate commands to our optical drive.

    I don't understand how to get there?
    it is about cmd> disk part> list disk etc?

    Not.
    In the CMS console, enter the letter of the DVD on which you have the Windows installation files, specifically the boot folder with the bootsect.exe file, for example:
    e: ENTER
    cd boot ENTER

    What are you asking about?
    Having the system installer running on the right? This is normal when you start the autostart from the installation CD. However, I do not recommend installing the system from this level.

    I mean, I don't have a win7 CD, it was an .iso image
    if it is written that the disk drive is win 7, then in the boting menu select boot with cd rom?

    It doesn't matter. For a computer, the iso image in a virtual drive is the same as a disc in a physical drive.

    Where is it written?
    You set booting in bios to USB HDD.

    ok, from the bios level, I still set usb hdd as 1 boot device and so it runs win normally from the hdd drive

    I have an idea, but I don't know if it will work, what if I do the D disk format and install windows there, then I do C disk format (windows is present here) then change boot from C disk to D?

    Check again if this flash drive starts up after disconnecting the HDD.

    It is a waste of time and the operation is very difficult to perform.
    From what I can see you have 2 hard drives. Do you have free space on the second to install the system there?

    Yes, both drives are over 200gb

    So you can install from the HDD. You have a detailed description in the link I gave. This is the best, fastest option, and it must work.
    You don't need to format the disk. It is enough to put the files copied from the Windows installation CD on the active partition and execute the mentioned command in CMD.

    Sorry, but I still don't understand point 7, I did everything as in your guide. But point 7 is impossible to pass,
    my BOOT drive has the letter "O" optical drive "i".
    I do not know what to enter in cmd

    Added after 5 [minutes]:

    Ok, I guess I understood

    ok, point 9 done
    Now 10. disconnect the C drive with the old win?
    or just change booting to my BOOT disk and install windows on C or O?

    The screen shows that the command has not been initiated. You must run the CMD console as an administrator.
    Unless you already have it behind you and have done it correctly.

    After the copying operation, restart the computer, in the BIOS select the disk to which you copied the Windows system from the disc, that is the disk with the "O" partition.
