Windows 10: Windows 10 iso installation errors

8gb and windows install from iso.

 

Is it a bootable windows 10 iso?

 

It works and can install windows. Out of curiosity, you've read all the previous posts?

 

Many read but some not understood. How come you cannot boot using a windows 10 iso and fix the problems?

 

He is able to boot the ISO and did a Clean Install of Windows 10. It goes all the way through (he runs it overnight) and then hangs in a loop:

See post#16: Windows 10 iso installation errors

 

Can you boot to the iso then click repair then open the windows advanced troubleshooting menu.
What happened with each:
startup repair
restore
command prompt
If you used command prompt which commands did you run

 

Which commands should I test?

 

Start with system restore: if there are valid restore dates start with the oldest and keep advancing to the most recent until you find one that works. IF there are none that work or if there are no restore points then move to the next option.
Next move to startup repair. If this fails then move to command prompt.
If this fails then move to command prompt > administrator: X:\windows\system32\cmd.exe > X:\system >
Type: bcdedit | find "osdevice"
This should display osdevice........... partition=C:
If the drive letter is different than C: please use the displayed drive letter for the next step
12) type: DISM /image:G:\ /cleanup-image /revertpendingactions (change G to the applicable drive letter)


Please use a camera or smart phone camera to take pictures and post images into the thread if you have any problems.
There are other commands and later in the day i'll be available to help if the above don't fix the problem

 

Do i do a clean install before? The loop appears to disappear upon shutdown, which I did, and I got a defaultuser0 account.

 

He has done several Clean installs so there will not be any useful restore points.

 

If you can open the iso > windows advanced troubleshooting menu > command prompt>
These are some troubleshooting steps to consider:
1) repair registry
2) fix boot
3) repair os
4) repair drive file system
5) remove pending update

 

Command prompt only opened a terminal.

There is a boot rescue method that requires a flash drive.

This is the next trial and error method to fix the problem.
This is the registry backup repair:



Let's see if this is a possible fix.


1) boot to the Windows 10 iso
2) it may take 5 minutes displaying the windows icon
3) Use the default settings for language, time, currency, and keyboard
4) click next
5) In the left lower corner click Repair your computer
6) click troubleshooting
7) click startup repair (it is expected to fail)
8) click system restore (it is expected to fail)
9) click command prompt
You should see a pop up with title bar: Administrator: X:\windows\system32\cmd.exe
This is the registry backup method:
For each step you must see sizeable file sizes for this to work.
If you see zeros the method will fail.
The command: dir
will be used each step to make sure you are in the proper location and check the size of the files
10) type: C:
11) dir
12) type: D:
13) dir
Choose the C: or the D: drive to proceed. It should be the windows drive and not the USB drive.
14) type: bcdedit | find "osdevice"
This should display the location of the partition and in most cases is the location of the affected drive.
For this post I will use C: however you should pick the drive letter that you found that has the windows files on your computer.
The proper drive will display: perflogs, program files, program files (x86), users, windows, etc
15) type or copy and paste: cd \windows\system32\config
It should display: C:\windows\system32\config>
16) type: dir
It should display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk, journal, regback, systemprofile txr, etc.
All of the file sizes should be sizeable. If it displays zeros then abort.
Make a new directory and name it backup or something similar.
17) type: MD backup
Copy all of the files into this new directory.
18) type or copy and paste: copy *.* backup
It should now display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk indicating the files were copied.
Change the directory to regback
19) type: cd regback
It should now display: c:\windows\system32\config\regback>
20)type: dir
It should display: default, sam, security, software, system etc
All of these files must be sizeable. If it displays zeros then abort.
21) type or copy and paste: copy *.* ..
It should now display:
DEFAULT
Overwrite ..\default? (yes/no/all):
22) type: a
It should now display: sam, security, software, system and that the files were copied.
23) type: exit
24) click turn off your PC
Remove the USB flash drive if you had changed your boot order. Otherwise you can leave it and power on your computer.

 

What's the purpose of the steps above, if I may ask?
