Windows 10: Significance of disk number when installing Win 10

Hi, I noticed the AU and the CU (not the FCU!) reversed the disk numbers assigned to my two disks at the stage when deleting existing partitions before installing Windows.

I'd appreciate any thoughts on the significance of this, or why it might have occurred given the problem I encountered after upgrading to the CU (below).

I have two disks, a SSD for my system disk, and a SSHD (see my specs).

The AU designated these as Disk 0, Disk 1 respectively.
The CU designated these as Disk 1, Disk 0 respectively.

Clean installing the AU works, and booting to Safe Mode from SHIFT left click Restart was fine.
Clean installing the CU works for normal boot, but booting to Safe Mode from SHIFT left click Restart failed with 0xc0000454 The Boot Configuration Data for your PC is missing or contains errors.

I also noted that when the PC restarted during its installation, there were two short lines of text shown very briefly on a black screen indicating a boot source hadn't been found (I couldn't get the exact text). That did not occur when installing the AU.

I suspect this difference in disk numbers may be related to my experience of upgrading from the AU to the CU, after which we were unable to resolve the problem of failing to boot to Advanced Startup options.

Whilst I have resolved that (by roundabout and unexpected means) I am concerned this may occur with future upgrades. Of course, I could take the back off the laptop and disconnect the second disk....

Thanks

this needs to be signficatnly updated

'Type Disk Cleanup in Start Search'

you always start the first step, not the 2nd or 3rd, like

1. hit 'win + s'

2. type 'disk cleanup'

for anyone new or unfamiliar with any of this, nobody is going to know what 'disk cleanup' is

when you introduce things, you never ever ever introduce things in an unfamiliar way to all the other users/ppl that do not know anything

-

i dont know if this 'disk cleanup' has any significant effect/impact for the majority of cases and common uses

or if there's any significant evidence backing/supporting this claim of doing this

but i have 2.33mb so i decided not to run it

not sure if this would increases performance by 125%

we need number and data to know if something is actually effective or not -- and how effective something is

we need data

 

Windows 10 compatibiity

Thanks for this.

Sony exited from the PC business the year before Win 10 was released. They maintain that running Win 10 might work "but will start to give problems", but could not elaborate.

In gross terms (CPU, memory, disk, etc), my VAIO meets the spec described at the link you sent me. However, there appears to be a significant amount of software installed by Sony. I was assuming that there might be some compatibility issues there.

 

Kari is doing much with PowerShell. He's about to release a tutorial about prepping a system for install with script. That may be helpful to you.

 

My M.2 SSD was pushed to 4th place ever since it's installation but rest of disks are in the order in BIOS depending on which SATA port are plugged in.

 

Ya my Samsang M.2 kept doing that, I hate that *Mad

I guess it`s just not seen like other ssd`s
