WINDRIVE Partition

Hello Pauli,

You are saying the same thing we tried to convey to the OP on the first page to no avail. If he indeed followed the advice on P1 where it clearly show via pics on doing custom install by deleting all (every partition) till you have one non allocated partition, he should not be facing these issues. This would be similar to using diskpart commands.

I purchased a Acer Aspire A715-75G last fall (exact same device as OP), it never had a WINDRIVE. There is a 1GB OEM recovery partition at end of drive (contains drivers and crapware). Have not done a total clean install on this device yet (keeping OEM partition for now) but have deleted the remaining partitions and re-installed. Resulted in same partition layout as you and I have shown already, with a 100MB UEFI MS Reserved Partition, C:Drive Partition and a MS Recovery partition (500MB) at end of drive, just prior to manufacturers recovery partition of 1GB.

Suggest you read through the entire thread. The OP is clearly not listening to anyone, rather has insulted every person here with his flip flop machine came with this or that OS. Do not appreciate anyone insulting CK as she is a kind, caring person as this OP has done (hopefully not aware he insulted a lady MOD).

@Ruroni,  Suggest you create a new bootable flash card via Media Creation Tool if in fact you are facing these partition issues and are even deleting all existing partitions (via installer or diskpart). Windows10 Installer does not create a WINDRIVE partition, ever. Have clean installed win10 probably way over thousands of times since 2014 for customers on many device types. Perhaps the flash card possibly got corrupted. It does happen as well as bad ISO images.

It appears you are doing an in-place upgrade rather than booting from USB using Boot Choice Menu. All this information was provided to you earlier that you have balked at.

Regards,

Edit: Please remember, I own this exact same model, and yes, it was tricky to enable Boot Choice Menu as that was also provided.

windows installer will not create the windriver partition, if you inadvertently deleted it thinking it was a windows partition, it will not be replaced as the windows installation did not create it in the first place.

as i said the windriver partition was created by Acer, it was there when you bought it along with the UEFI shell.

it is not required for windows or any other OS, drivers that were in there may well be out of date now.

you can't get it back (unless you create it manually and populate it with up to date drivers),

you have said that you do not want to create it manually. 

why would you?, it is unnecessary and now it is gone you can use the space for important stuff like your data.

why do you want to remove windows boot manager? are you not going to install windows?

it may be possible to do it from within the UEFI shell but, i don't know enough about UEFI shell commands to advise further, you can do it from within Ubuntu, but if you are going to run windows, there is no point in attempting to remove it.

My Windows 10 Installer only creates 3 partitions 

1 partition = 16 MB Microsoft Reserved Partition (MSR)

2 partition 8 GB = WINDRIVE, which I searched first time I saw it on the Google that's why I know exactly what was and how much space it had. I searched for it on Google to hide it from the My Computer because I didn't want that partition to be seen there on the list since I won't be using it, It was NTFS formatted and It had some Microsoft Windows files on it also.

3 partition my unallocated hdd free space

Is not creating recovery.

When you are installing Windows and delete all partitions so that you have only big unallocated space.

Select that space and click next to continue. Installer should create all those partitions, see also my screenshot of diskpart listing. (I created partition 4 Data (D:) all other partitions are created by installer.)

Older Windows versions didn't necessary create separate recovery partition in clean install, recovery environment was included to some other partition.  You can check that location by opening command prompt (CMD as Administrator) and giving command:  reagentc /info

EDIT:
P.S. Don't worry about drivers. I have (now retired) Acer Aspire 5738g, introduced May 2009, and it's running Windows 10 Pro v20H2 without issues. According to device manager all devices are working and I have never download and install any drivers manually. All are installed by Windows.

For new computers it's good to get latest BIOS/UEFI (and maybe drivers for display adapter) from manufacturer.
