Converting System To UEFI To Support 4TB Disk

Aug 12, 2015

Just converted my systems to Windows 10. Working well, so far. I would like to install 4TB disks on a couple of the systems and understand that I need to use UEFI. Looks like my ASUS P8Z68-U GEN 3 MB supports UEFI, but I don't understand how to enable it. The other system has ASUS B85M-E mother board. I've seen some one paragraph descriptions, but they don't really walk me through the process.

1 - Can I upgrade my existing system without a complete Windows 10 reinstall? I have lots of apps installed so I'd like to avoid complete system rebuilds.

2 - Due to legacy use of Mirrored drives, I'm using the Intel RAID stuff, although I no longer need it. Will that be a problem? SSD and other disks are JBOD. I'd like to get rid of that, but I think that does require a complete system reinstall since disabling the RAID wipes the disk.

Looking for step by step process to convert a system to UEFI to support 4TB disks?

Computer Hardware May Not Support Booting To Disk

Aug 22, 2015

I'm trying to install Windows 10 clean install on my laptop via USB. I've gotten to the point where I'm configuring the hard drive and I got the message in the title "Windows cannot be installed to this disk"

I then deleted the existing hard drive and had roughly a TB of unallocated space. Created a new partition and formatted only to get the same message.

Background: Purchased an HP Elitebook 8460p a month ago running Win7 Pro. Can't quite remember how it was running when I first started it up. I upgraded to 10 a little over a week ago using window's upgrade. Immediately I felt it was running really slowly. I have 10 on a desktop which runs really smoothly. I checked and found that the laptop was consistently running at 100% disk usage. I looked up and tried various different fixes to the 100% disk usage problem including removing BITS and superfetch.

I felt that maybe there was a problem with Win 10 on the laptop so I used the native revert to 7 program in windows 10. I found that even in 7, the computer was running terribly slow. I decided to just do a clean install of 10 and here is where I am now.

Specs:
Intel Core i5
8GB DDR3 SDRAM
1TB HDD

I've read other threads here and elsewhere regarding the SATA device mode changing from IDE to AHCI. I just checked and it is already set at AHCI.

Cannot Upgrade Due To Unsupported Disk Layout For UEFI Firmware

Dec 13, 2015

I've had Win10 installed for ages and no problems until Upgrade 1511 came along. How come Windows 10 worked all that time and now refuses to upgrade?

Upgrade to Windows 10 Home, version 1511, 10586

error message:
"Windows 10 couldn't be installed
*Windows couldn't be installed because this PC has an unsupported disk layout for UEFI firmware."

Installation :: How To Install On RAID 0 Non UEFI System

Feb 10, 2016

I've rescued an old small server(working with Red Hat enterprise -- but I can't have the OS as it's licensed by the office) from our office --was being chucked out but looks quite good to me.

4 SATA bays populated with 4X 3TB HDD's (the HDD's were mine BTW !!!). I'm thinking of using this as a NAS server - 16 GB RAM and decent Intel CPU (i3 equivalent -- good enough for media server).

The only problem is that it's MBR BIOS and I have two RAID 0 arrays consisting of 2 X 2 3TB HDD's.

Installing Windows though -- No HDD's seen !!! yet there's 12 TB of them in the system.

The RAID is onboard --not a separate RAID controller.

Should I remove the HDD's and send the server on it's original journey to a one way trip to the City's TIP.

(On board VGA good enough also for running a GUI - if I can ever install an OS on it -- preferably W10).

Performance :: System Process Reading Disk 100% And Making System Very Slow

Dec 19, 2015

I found out that the hard disk is 100% utilized. In Task Manager, the process that utilizes the disk the most is ESET Service. If I open Resource Monitor there are many instances of the System process that are reading the disk, not writing it. I have two partitions on my disk - one for the system and the other one for data; the extensive disk reading is done for Pictures (I assigned a folder with pictures, about 140 GB in size, to the system My Pictures folder) on the data partition.

I am not running any tests in the ESET Endpoint Antivirus software and it seems to me that the high disk activity starts when I do not do anything and just e.g. browse Internet or look at something. So, it feels like Windows is doing something, but what it is and how I can influence it. If it were disk optimizations I think I should see also disk writes, not only reads. Could it be that Windows is doing something automatic with Pictures, Documents, etc.?

I wonder what is going on - I dislike the fact that something is going on with the hard disk, making is 100% utilized and making other work very slow and non-responsive.

Drivers/Hardware :: Converting MBR To GPT For EFI Boot?

Nov 27, 2015

I've just recently re-installed Windows on my laptop. I had the hard drive set to a GPT format disk since my system supports and previously used UEFI boot, but this install wouldn't allow it so I just went to MBR again..

Is there a way to convert the currently MBR type disk to a GPT format (without losing the current Windows installation) so I can resume using the UEFI format boot? I'd like to later dual boot Linux and I'd pref having a UEFI load over the MBR when that time comes.

Installation :: Transfer System Disk Image To SSD

Feb 10, 2016

I have created a disk image of the system disk, C: with the disk image software in Win 10 backup. The system disk was 70GB with 40GB of files. When I tried to write the image to the SSD the Win 10 install software said the disk (120GB= 110GB) was too small. I reinstalled the windows disk booted and shrank the system disk to just under 60 GB and retried the process with the same result. System is Win 10 32 bit on an old Acer netbook.I would like to be able to transfer the installed files to the SSD.I have looked at the tutorials for creating a system image and also how to create hardware independent image for installing win 10

Performance :: How To Make System Recovery Disk On SD Card

Dec 4, 2015

I am using a small tablet with Windows on it. It already has little space (32GB which is actually 29 GB), with Windows eating up a ton of space. Now, with a virtual partition on the tablet reserved for system recovery, I have less than 5 GB left, not enough for Windows to update. I would like to merge the virtual partition so as to get ~5 GB extra space, in or to do so I would like to make a recovery disk on a SD-card.

The problem is, Windows does not seem to recognise the SD-card when I try to make a recovery disk! Is there a workaround, or did I get the SD-card in vain?

Installation :: System Setup With Both Solid State Disk (SSD) And HDD

Dec 15, 2015

I hope shortly to receive a "pre-owned" Dell M6800 laptop with a 128GB Solid State Disk (SSD) and a 750GB HDD.

It comes with 8.1 installed (shudder) and I will upgrade to 10 immediately as I couldn't tolerate 8 or 8.1. Once I've done that, I'll need to transfer all my applications and data (which will be tedious I know unless there's some trick or clever tool/application to do it).

Aapart from the OS what should go on the SSD, and what on the HDD. Looking at my current system, the Windows directory plus Program Files, Program Files (x86) and Program Data run awfully close to 128GB, so this isn't quite as simple as Windows & Apps on SSD, with everything else on the HDD and use junctions if necessary to point to data on the HDD.

Drivers/Hardware :: Can Remove EFI Partition From Non System Disk

Aug 17, 2015

I have a drive that I want to use as a backup drive for a Windows 10 machine. The problem is the old drive has a boot partition on it that is making Windows 10 go nuts every time I plug it in. If I wait until after the machine boots and then plug it in via USB adapter then I can get to the files but I want to install it inside the machine permanently.A photo of the Disk Manager is below. How do I (or should I) remove that EFI System Partition? The Disk Manager won't let me do it.

Installation :: Move System Partition To Primary Disk?

Jan 26, 2016

So I recently formatted my Windows 8.1 system and installed Windows 10. But it seems that the setup decided to set my System parition to a separate HDD (G: ) and put the bootmgr and all the boot files there, instead of using the left-over 350MB System Reserved partition on my primary SSD that Windows 8.1 had used. So of course now if I removed that disk, I wouldn't be able to boot anymore.

So what'll be the best way to move all of the boot files and system partition setting back to my old 350MB System Reserved partition? Will I need to disconnect all the other drives and do a repair install of Windows 10? Or can I manually move the files and partition settings over? The old partition is still marked as Active, so maybe I can just move all the Boot related files from G: to the 350MB partition and it'll just work? Maybe mark G: as INACTIVE too

Performance :: System And Compressed Memory Slowing Down Disk Operation?

Feb 23, 2016

I have win 10 64-bit home on a 4th gen core -i5 laptop. I have a WDC 1T 2.5" USB3 drive. It is about half full. It used to do 60-70MB/s write speed. Since a few days ago, I noticed it has slowed down by a factor of 5-6 to 10-20MB/s. While copying large files, I watched what's going go. The System and compressed memory process was doing a lot of read and write on the disk. If the copy speed reported by the dialog is say 15MB/s, then system compressed memory process is reading 15MB/s and writing 30MB/s. It looks like this process is reading back the content written and writes back. It is consistent over reboot with several large files from 200MB to 7GB in size.

A couple of weeks ago I did a file backup. I created a 5GB virtual drive on my SSD and dumped all files to be backed up. Took only 5 minutes to copy the 5GB files to the virtual drive and copy the file to the WDC disk, at around 67MB/s, typical of this type of portable drives. While I was wondering what was going on, I tested the same files with a USB3 dock and a 2TB Seagate drive. Write speed is about 150MB/s. So I thought it was not a problem with all disks. The WDC drive has no compress to save space option, BTW. I wonder what's going on. I have AVG antivirus and I turned it off while copying and same slow 15MB/s speed.

The Program Don't Support The Project

Sep 6, 2015

I have recently upgraded to Windows 10 on an eight year old laptop which previously was running Windows 7. Everything appears to have gone well and I am enjoying the new operating system. However, every time I boot up and get to the desktop a small box appears on the screen with the following wording "Warning. The program don't support the project" with an OK button and an X close button. Clicking on either of these closes the box and I simply carry on as normal. What concerns me is the bad grammar "don't support" and I am concerned it might be some sort of malware.

I attach a screenshot.
