Windows 10: Install Windows 10 without deleting all previous partitions on the harddisk.

I was trying to install windows 10 in my Asus X441N which has no lagacy boot option so I had to install it in UEFI mode. In the setup I selected an unalocated space of 100GiB and pressed next and it created three partition Windows, System, Recovery then complained about the boot order of the partitions it just created itself : why it would do that?. I choosed to continue ignoring the complain then the instalation started and a window popped up showing error that it detected the EFI partitionThe System partition it just created in the previous step was NTFS not FAT32. I searched in the internet for the problem, and found answers like -

• Delete all the partiions in your harddisk
• Rename the EFI folder in the bootable usb to NoEFI or something else
• format the System partition to fat32 using diskpart I don't know when

I can't delete all the partitions and the other two didn't worked.


Then I tried to install it mannuallyApply the images with dism with the help of this documentation https://docs.microsoft.com/en-us/wi...stem-and-recovery-partitions#apply-the-images. Well I didn't followed every steps in there. I've created the partitions using KDE partitioner, ignoring the recommended orderdidn't find any -

• System partition of 116 MB - fat32
• Recovery partition of 450 MB - ntfs
• Windows and Data partition of 100GiB - ntfs

Then just followed the steps of the above mentioned documentation from the the cmd of the bootable usb.

I'm pretty sure I used the correct drive letters during these steps then rebooted. In the OOBE it showed that Windows setup was unable to configure windows in this hardware.


So, Can someone help me to "Install Windows 10 without deleting all previous partitions on the harddisk" by any method?

Delete my W10 Partition

Do you want to safely delete your Windows 10 partition and use only Windows 7?

If Yes, then boot to your Windows 7, run msconfig, go to "Boot" tab, you will see something like this :





Choose "Windows 7" and click "Set as default", then choose "Windows 10" and click "Delete", restart if asked or necessary.
Now the boot information for Windows 10 has been deleted and you can safely delete your Windows 10 partition (make sure no important files are on the Win10 partition). To delete and extend your partition you can use many partition manager tools.

 

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

Windows 10 Setup without formatting whole Harddisk, only C-Drive delete, new partition and install

I want to Format my C-Drive in order to reinstall Windows 10 OS

But when the step comes ''which drive you want to install'' i format the C-Drive and suddenly it says i windows cannot install in that partition, if you know what i mean

I mean i delete the C-Drive then make C-Drive partition again ( i have other 2 partitions without C-Drive and they have Important Data which are not saved+ i don't want to delete those partitions for installing Windows) and it don't take that partition to
install Windows, so then i had no other way but formatting Whole Harddisk and make partition again

All my non-backuped data gone

How to get rid of it ?
