HP Pavilion g7 with Win 8 SL

Question

Windows

Good afternoon. A laptop was purchased with pre-installed Windows 8 for one language. There was an urgent need to put a 7-ku. I made an image of all sections with an acronis. Demolished partitions and began to install. (Before that, there were dances with HP UEFI. Disabled Secure boot. Enabled Legacy boot and booted from the disk with grief in half). If you start to divide the disk, then it does not even allow you to select a partition. Writes "Windows cannot be installed to this disk. The selected disk contains
an MBR partition table. On EFI systems, Windows can only be installed to a GPT disk." I went to the console. Diskpart - select disk 0 - clean - convert mbr" I selected the partition and it seems like the copying went on, it hangs at 0% on unpacking the files. What I just didn’t do. There are always only 2 results described above.
For the sake of interest, I began to install 8-ku from the disk. All the same. But! If you delete partitions and start installing on a partition that has not been created, then the installation will go through and even everything will load. It doesn't work with 7. What to do? Already tired of fighting with these new innovations.

Answer 1

After much torment, the following helped: (instruction from the root tracker)
First of all, go to the BIOS settings (for HP Pavilion - press F10)
Go to the "System Configuration" - "Boot Options" section We will see the
following
We are interested in the following items:
CD-ROM Boot
Legacy Support
Secure Boot
We need to enable CD-ROM Boot "Enabled"
We need to enable Legacy Support "Enabled"
We need to enable Secure Boot "Disabled"
When trying to enable the Legacy Support item, a message pops up (Changing this setting may make the system unable to boot the OS. Do you want to make this change?) to which we answer YES.
But after rebooting the BIOS, it returns all these parameters to their original state.
For a long time I dug into the internet why this is happening, I did not find the answer.
After a call to those HP support (without receiving a single intelligible answer, such as take it to a service center or install Windows 8), it suddenly dawned on me that these parameters may depend on other parameters.
After several attempts, I succeeded! It turns out I was right.
And so, in order for the Legacy Support function to work, you need to do the following:
1. Set the Secure Boot item to “Disabled” mode
2. Select the item (it will become active) Clear All Secure Boot Keys
3. Then enable Legacy Support
4. Exit BIOS F10 .
Now, when rebooting, everything works as we need, that is, to install at least Windows 7, at least Windows XP, or whatever your heart desires!
In my case it is Windows 7
Further guidance was taken from rutracker.org/forum/viewtopic.php?p=56443462#56443462 provided by user oneg1 Booting
from the Windows 7 disk. After copying the files and the
first window appears, press <Shift+F10> to exit in com. line.
Further.
After entering each command, press and wait for the prompt after executing the command.
We call the DiskPart utility:
diskpart
We call the list of disks:
list disk
and since it is only one, Disk 0 will also be in the list.
Pay attention to the GPT column .
If there is (*), then the disk has a GPT markup.
Set focus to disk:
select disk 0
Delete all partitions on the disk:
clean
If the disk is GPT (see above), then convert it to MBR
convert mbr
Create a system partition:
create partition primary size=80000
where n specifies the partition size in megabytes (MB). If no size is specified, the partition takes
up all the free space in the current area. For an 80 GB partition, specify: size=80000.
Format the partition and assign a label:
format fs=ntfs label="System"
Make the partition active:
active Assign the letter
"C" to the partition:
assign letter=C
The system partition (C:, System, primary, NTFS, active) has been created.
Now on the remaining unallocated space we will create an additional logical partition
under the data (file dump): D: - Data (set the letter and label according to preference).
create partition extended
partition will take up all the remaining space.
In the additional partition, create a logical one:
create partition logical size=300000 with
a size of 300 GB.
Format the partition and assign a label:
format fs=ntfs label="Data" Assign the letter
"D" to the partition:
assign letter=D
Create another logical partition on the remaining space:
create partition logical
Format the partition:
format fs=ntfs
Assign the letter "E" to the partition ”:
assign letter = E
There are 3 partitions on the disk: for the system C: System, logical D: Data and E: (assign the label yourself).
Next, we exit the disk management program:
exit
And exit the command line:
exit
The installation continues as usual. To install the system, select partition C:

Answer 2

It turned out that the whole thing is in the USB connector used.
Those on the right apparently have USB 3.0. Not marked with color. There are no inscriptions. Conveniently located, 2 nearby, apparently all of them used.
I flipped it to the left and lo and behold ... It worked ...
Keep in mind. Can anyone help

Answer 3

After copying and unpacking the files, the laptop reboots.
The installation does not go any further, it crashes into a black screen.
When you select "Normal boot", it reboots, and again the black screen.
In which direction to dig?
