Maintenance :: Unused Partitions Take Lot Of Space And Dual Booting

May 21, 2013

So recently i bought a refurbished/used Samsung ultrabook (NP540U3C-A01UB )

One of the features is that is has : (500GB with 24GB ExpressCache - Technology)
Which I don really understand.

I've also noticed that the system has a lot of partitions that are taking space and are largely unused. I've had the computer for about a month and i use it everyday almost and so far a lot of the partitions havent been used.

I don't see a reason why to have those.

So can i Erase them??

Please notice 2 disks. I know the larger one is used for C: and the other for the ExpressCache???

Also notice that disk1 is empty. Pretty much all of them are, with the exception of 2 (C: and the partition right of it)

What is it used for?? How can i find out?? Whoever installed this system made a mess.

Here is a second part of my question:

For work reasons I have to have a Ubuntu machine and I thought I could just dualboot and use the partitions that are unused. Which is why i care about the unused space.

I have used virtualbox in the past but it was really slow. I need a responsive system and virtualization is no longer an option.

So my question would be how can i accomplish the dualbooting?? Specially taken that i have UEFI/random partitions in my system.

I know there are a lot of tutorials out there but none come close to my drive mapping/situation.

Just don't wanna destroy my system while trying to get the dualboot working.

ASUS K75DE Windows 8 And 7 Dual Boot - Boot Options Grayed Out In BIOS

Dec 15, 2013

I just got a refurbished ASUS K75DE laptop, and it came with Windows 8 on it. I am wanting to run a dual boot with Win7, so I disabled fast-boot just fine, and went into the UEFI BIOS and disabled the secure boot.

While I was there, I did like I have always done and set a BIOS boot-up password. I then proceed to boot to my Win7 installer USB Flash drive, but I was running low on battery power so I aborted the install and shut the computer down to try again later.

Now however when I get into BIOS to select boot priority, all options are grayed out except for system time and a few other non-essentials. At the bottom of the first BIOS screen it says "User Level : User" and I can't seem to find a way to reverse this issue. So now I'm stuck, can't boot to anything but the HDD because it is first by default.

Setup Installation :: Artificial Dual Boot - Mount Both SSDs In HP Case And Switch To Either One At Boot?

Feb 18, 2013

Late last Fall I bought a new Desktop, an HP H81414, with Windows 8 installed with the intention of installing Windows 7 on an SSD. I migrated Window 8 to an SSD, removed that from the system, installed new SSD and put Windows 7 on it. Both worked fine. I wound up with 2 SSD's. capable of running on the EFI BIOS machine with Secure Boot turned off. I later bought a new laptop with Windows 8. I found the Win 8 with Classic Shell to be very acceptable.

What I would like to do now ,if possible, is to mount both SSD's in the HP case and switch to either one of them at boot.

Setup Installation :: Dual Boot - Removed Old HD Now No Boot At All

Apr 28, 2014

I had windows 7 running on my computer. When windows 8 came out I used a second harddrive as the windows 8 installation drive. Windows 8 automatically setup a dual boot system where every time I started the computer it took me a windows screen where I could select either windows 7 or windows 8. This has been going on since Windows 8 was released.

I decided it was getting old so I decided it was time to remove the old windows 7 harddrive. I tried doing it inside the windows 8 dual boot screen but could not find an option. So I decided to reformat the windows 7 harddrive. I did this in command prompt mode. After doing so when my computer restarted it said it could not find any harddrive to boot. Windows 8 is installed on the other harddrive, the one that was not reformatted. So how do I get it to start using that harddrive as the boot drive? I checked my bios and even physically disconnected the old HD that had windows 7 on it, but none of that seemed to work even though the Windows 8 HD is definitely in the boot order in the bios.

Maintenance :: Win 8 / 7 Dual Boot Results In Chkdsk Run At Boot?

Jun 8, 2013

I am dual booting Windows 8 and win7. I actually have Windows 8 installed on its own hard drive and win 7 installed in its own hard drive. The win7 hard drive has been in use for the past 2 years and I have had Windows 8 running for about a week now. I purchased another hard drive for Windows 8 and left the old Win7 as it was.

I also have 3 other hard drives in the system. Everything is formatted NTFS.

So my system is as follows

Drive C - Boot Drive - I physically swap out the dedicated hard drive for Win 8 or Win 7
Drive D - internal 250 GB sata drive
Drive F - internal 250 GB sata drive
Drive H - internal 250 GB hard drive.

I have been running this config for about 2 years under Win7 with no problems.

The problem that I have now is when I swap the boot drive and boot up a different OS than last time (Like booting Windows 8, powering down system, swap boot drive, boot Win7) the system always says that there are problems on the 3 non-boot drives. It runs chkdsk(it least that is what it look like) and processes the 3 non boot disks one at a time which take about 10-12 minutes for all 3. Most of the time it finds no problems, but about 1 out of 5 boots will find a problem with one of the disks and then fixes it. The disks seem to be OK while I am running. I then power down and swap boot drive and reboot the other os and we start all over again. I am powering the system completely down for each reboot to make sure that the disk cache is flushed.So far the disk problems have been fixed by chkdsk at boot, but I am sure the day will come when the disk cannot be fixed and I will loose data.

Deleted All Partitions On Surface Pro Now Cannot Boot

Mar 2, 2014

I used Acronis to delete all partitions on my Surface Pro. So there is no recovery, C drive, nothing at all. Just a blank SSD drive without any partitions. Now the Surface Pro refuses to boot to any of my USB sticks so I can clean install an OS like I wanted to do. I've verified both of my USB sticks are boot able, as I'm able to boot my desktop computer to them in order to install an OS. But when I try to boot the Surface Pro Gen1 to the USB stick, I get a quick squiggly screen and then I'm dumped right into the system BIOS. I've made sure to power off the Surface Pro, then hold down volume- while pressing the power button, then releasing volume- after seeing the Surface splash screen. But it never goes to any sort of boot menu or anything. Just takes me right into the EFI BIOS.

Setup Installation :: Convert Dual Installation Into Dual Boot?

Dec 11, 2013

I cloned my existing Windows installation (8.1 pro, 32 bit) onto my new SSD. I got everything up and running, and I still have my old Windows installation on one of the partitions of my HDD.

Can I turn this setup into a dual boot?

I think this could be useful, in case the new installation gets borked, or in order to run an effective malware scan on the SSD, etc.

Setup Installation :: Recreate Or Reinitialize Hidden Boot Partitions

May 15, 2014

I have a very peculiar issue; after using various disk imaging tools such as Macrium and Paragon, my boot partitions seem to be strangely corrupted. The effects of this corruption are:

1) Plain-text boot menu instead of the new graphical boot menu,
2) Long delays before the boot menu is shown,
3) Even longer delays when doing native VHD boot, after choosing the boot entry from the menu.

I have done a lot of testing and experimentation, and on a virgin fresh installed system from the Windows 8.1 setup ISO, these symptoms do not appear. Only after I have imaged the system using the imaging tools above, do these symptoms start appearing. Unfortunately, just copying my main Windows C: partition using the same imaging tools re-creates the same issue. So I cannot rely on these partitioning tools.

I need a way - a set of commands - to re-create the boot partitions, re-initialize their BCD stores, etc. so that I can normally boot from my C: partition, as well as native VHD boot.

Needless to say, I want to avoid having to completely reinstall Windows on my C: partition, as that would be extremely time and effort prohibitive, if I only knew how to re-create and/or re-initialize just the boot partitions in question.

Windows 8 Fails To Boot After Booting Into Windows 7 - Dual Boot

Sep 15, 2014

I have a Dell Inspiron 17, 5000 Series (1.7 GHz Intel Pentium 3558U, 4 GB Ram, 500 GB HDD). It came preloaded with Windows 8.1. I needed Windows 7 so I partitioned the main drive and installed Windows 7 in 100 GB of partitioned space. After swapping between the Windows 7 and 8 Boot manager. Ended up choosing the Windows 8 manager.

My problem comes in when I boot into Windows 7, then when I shut down and try and boot into Windows 8 it will hang prior to the boot manager (of Windows 8). I have to press and hold the power button to hard shut down. Once I do that and reboot, Windows 8 Boot manager and Windows 8 boot ok.

So Windows 8 will boot fine if I was last in Windows 8. However if I was last booted in Windows 7 then go to Windows 8 (or try and boot into 7 again, but using the 8 boot manager) it will hang at boot. I've used all the command checks with Windows 7 and 8. Found no errors. I can't reinstall Windows 8 as I don't have recovery disks, plus the computer came from Aarons Rent to Own (they had no issues me doing what I wish with it).

When I switch and use the Windows 7 boot manager I can boot back into Windows 7 even if Windows 7 was my last boot. But like when using the Windows 8 boot manager, I am unable to boot into Windows 8 if Windows 7 was booted last. But Can boot to Windows 8 if Windows 8 was booted last.

Installing Windows 7 To Dual Boot?

Feb 16, 2013

I have new pc that has windows 8 pro installed. I would like to dual boot with windows 7 because certain software for work is not compatible with win 8. I was reading that I can create a vhd from windows 8, boot to the windows 7 installation media and install win 7 to the vhd, then I have the option to select win 7 or 8. Am I missing something here or is it as easy as this? Also do I need Win 7 ultimate or will he professional one work? I do not want to partition the hard drive.

Dual Boot And Windows 8 Reset

Jun 2, 2013

Well, I had a dual booted machine booting Windows 8 and Ubuntu.

Windows 8 was starting to play up so I decided to completely reset the computer. I backed everything up, booted to Windows 8 and hit the 'Reset PC' button.

After answering some questions (full erase, whole disc etc), it informed me that it was going to restart. I clicked accept.

Short Story:
- Corrupted Windows 8 partition
- Corrupted Windows 8 recovery partition

Long Story:
Instead of rebooting back to anything, I got left sitting at a grub rescue prompt. From there I told it to boot windows 8.
I then spent five minutes staring at the booting screen. Nothing happened.

I powered off and tried again, this time pointing grub rescue at the windows 8 recovery loader partition. Well, initially that looked like it worked. I got the nice metro UI, and chose 'reset this PC' It then informed me that the recovery partition was missing some files. The only other option was to shut down.

I tried booting just plain windows 8 again, but had the same problem as before (nothing happening), And now when I try to boot the recovery loader, Grub tells me the EFI file isn't where it expects it to be. (Interestingly, how are you meant to boot to this without having a non-windows bootloader?)

Additional Details: Computer: HP Envy M6-1206TX. Pre-installed with Windows 8. Bought about 1 month, 1 week ago.

The Questions:
Since windows 8 came pre-installed, I don't have a Windows 8 disc, are there any possibilities for me to get back windows 8? (other than contacting the store I purchased it from)

After going through the license agreement, my interpretation is that I still have a license for Windows 8, but I am not under their limited warranty (due to dual booting). I do not wish to buy another license, as I already have one.

One last question:
If you acquired the software on a disc or other physical media, your proof of license is the genuine. Microsoft certificate of authenticity label with the accompanying genuine product key.

Neither my laptop, nor the box, nor any of the paperwork provided in it had this 'certificate of authenticity.' I suppose that means I have no legal rights to the software. Who's fault is this, HP, Microsoft, or the store I bought it from?

Fine To Dual Boot Windows 8.1 With Win 7?

Feb 24, 2014

I have previously posted about the recommended Windows OS for my new laptop... and Then I decided to install Windows 8.1 Pro alongside my previously installed Windows 7 Ultimate (32-bit)... Is it OK to install and dual-boot Windows 8.1 Pro with Windows 7 Ultimate?

And also tell me about the partition size allocations for both Windows, I have two partitions each of 24.7 GB for both the OSes, is this size worth applicable?

Dual Boot Without Re-installing Windows?

Jul 30, 2014

I have created dual boots before but in each case I did it the "usual" way by doing a fresh install of a second OS on a new drive (or new partition) and then letting the newest installation figure out how to arrange boot loaders or boot managers or whatever, i.e to figure out the dual boot parameters for me.

In this case I want to set up a dual boot using what is now 2 separate drives each with its own complete install of Windows. Of course, I can boot to one or the other by disconnecting the drive for the one I don't want to start up, but that is obviously a hassle.

Is there an easy way to set it up so that one of them (Win 8.1 pro) actually recognizes the other and asks me which one I want at boot up. I know if I re-install one of them I can do it, but I want to just set up the dual boot, and not touch either of the OS installations per se.

Dual Boot - Windows 8 Locks Up

Nov 14, 2012

I have two hard drives One is a SSD and the other is a WD 64 MB cache 2 terabyte drive. I have Windows 7 installed on the SSD which works fine. I later, when I received it, installed Windows 8 on the other drive for a dual boot. It works, the screen comes up allowing me to choose between the OS's. Like I said picking 7 works fine but when I go into 8 it boots up, shows the Metro and is locked solid. I havent waited more than 5 mins but i get tired of it locking. I have 16 gigs of Kingston Ram, 2 ATI 6950 with combined 4 gigs. AMD 8 core and a ASUS motherboard. Everything was bought this year. Except for the Video cards. I am trying to update the ATI software but it is locked so i cant.

Windows 8 / 7 Dual Boot Incompatibility?

Dec 2, 2013

I've been doing the above ^^ for some time now. I've been using W8.1 as the main OS for my notebook. Yesterday I rebooted into Win7 to poke around. Every time that it said 'Starting Windows' it bluescreen (very rapidly) and restarted.

I tried the disc auto-repair, and this cut the bridge to W8.1 of course. When I tried Win7 it then said that there was another problem. The logon screen appeared, as if in safe mode, then produced numerous errors about being untable to log on or start logon services. I could not resolve this.

I eventually decided to try the manufacturer inbuilt restore of Win7 while leaving data alone. This seemed fine until it says 'preparing Windows for first use', then it said that the installation was interrupted (not by me or power use). I tried this several times but no use.

Shortened, I could not get back into Win8, I tried all the repairs, though it should only have been a bootloader issue, right? The Win8 bootloader will look back and see Win 7 and offer both. I formatted that partition, reinstalled Win8 on that partition, removed all data from the Win7 drive and then tried a complete reinstallation of the entire hard disk with the manufacturer restore disks. This worked.

I would like to poke around with W8.2 when it comes in the Spring. I need to understand what happened. My top two guesses are:

1. Minitool Partition manager, I suspected that program of being ... ruthless in hard drive partitioning and resizing in the past.

2. Perhaps some incompatibility coming from Win8?

(ie Microsoft Office '10; various Online Games) ...

And will I have to reinstall drivers? (ie Sound/Graphic Drivers)

Windows 8 Missing On Dual Boot Start Up

Apr 24, 2013

I bought a new laptop 350gb HDD with Windows 8 64bit preinstalled (no disc came with it) however I needed win7 32bit for my job since the softwares used are only compatible with old win version. I managed to back up my Windows 8 before I partitioned my HDD into 3 drives and installed win7 ultimate 32 bit on a different partition. I remember that my Windows 8 was installed in Drive C (100GB) while I have 80+GB for Shared files on Drive E and the rest of the memory are for Drive D where I installed win 7 and I labeled each drives accordingly. At first everything was working fine on both O.S, it was giving me the dual boot option at start up but I forgot if I really have tested running both O.S. before I gave my laptop to my supervisor and asked him a favor to intall the softwares for work purposes.

My supervisor then approached me and said that there might be some incompatibility issue with the updates I have on my win7 coz some applications don't install so he asked me if its ok if he reinstalls a new win7 so I said yes since Im confident that its will work fine and I have backed up my Windows 8 anyway, in short, I left everything into his hands. Later, he then got back to me and told me every job related softwares now work except that my Windows 8 now doesnt show and yes, dual boot option is not there anymore and it boots automatically to win7 like Windows 8 is not there.

I've read some forums how to check if your O.S are still there and it could just be a boot up issue and use of Easy BCD might work. I have attached images below for your reference. Now what I'm confused of is that my Windows 8 appears to be in Drive D and win7 could be in Drive C, which I'm thinking if they were exchanged when my sup reinstalled win7 or he may have overlapped my Windows 8. Im pretty sure he knows which drive is for which O.S since I labeled them. Now Im afraid to use EasyBCD on the wrong drive and I cant approach my supervisor anymore to bother him again since he worked on my laptop for almost the whole day at work.

- if both o.s. are still intact and recognized
- why the Drive letters got mixed up and how to check which drive has which o.s coz it seems like both drives has a part of my work related applications (didn't put personal files yet on win 8 when I had both o.s installed)
- is Drive D really is my Windows 8 now?
- does Easy BCD really work
- how to use Easy BCD to get my Windows 8 to boot up to or both of them to show at start up without corrupting my work related softwares

Dual Boot - Windows 8 Goes To Black After Install

Jul 30, 2013

I've recently installed a dual boot, Windows 7 and Windows 8. The installation went fine but then after a very short time my Windows 8 Screen goes black. I had to press the power button to exit.

I've checked the Power settings and ensured the "Turn off display" was "never". I also updated my Video drivers thinking that might be the problem. Both to no avail. I've done a "Refresh" and a "Reset (which took 3 hrs). Again, all was fine for a short time, but while exploring the OS, again the black screen.

I followed... re-formatting the hard drive during the new installation, trying generic video drivers and doing Resets and Refreshes. None of that worked and still doesn't. The installations do complete as before, but I don't have enough time to download new updates to perhaps correct whatever problem(s) there are before all goes black after a few minutes. As I stated before I have to hold down the power button to exit.

If this is a clue, once the screen goes black and I revert back to Window7, before loading, the File System on ALL drives, including C and the Windows 8 partition has to check for consistency before Windows 7 boots up.

I've been quite busy and haven't had a chance to try re-installing again until now. Thinking the problem might have been the actual drive I used for previous attempts (it was a SATA external drive which by the way I previously used for a dual boot Vista/with Win7), I then created new partitions on 2 different USB connected external drives and attempted to install. It wouldn't do the install on either one. I received messages "Setup does not support disks connected through USB or Firewire,.... my USB drives are connected directly to computer not a hub. So I'm forced to use the SATA created partitions for the installations. (Disk 1)

If it makes a difference, through Disk Management, I've deleted the Windows 8 installs from those partitions then re-created a "New Simple Volume" before trying again. I even tried creating another partition on C but it wouldn't allow an installation saying it was a dynamic drive. Prior to me creating that additional C partition all were Primary but now they're all Simple Volumes as per the color codes.

I have two OEM Windows 8 installation disks, I've tried both.

DUAL BOOT - How To Install Second Copy Of Windows 8 X64

I have ASUS laptop which came with pre-installed Windows 8.1 X64.

When I try to install a second copy of Windows 8.1 X64. I get the following message

"Windows can not be installed to this disk. The selected disk is of the GPT partition style"

I found suggestions at

#1 - How to "Clean" or "Clean All" a Disk with the Diskpart Command ... [URL] ...


I would like to know

1. Clean command of Diskpart will mark data on the HDD as being deleted. How do I recover my original Windows 8.1?

2. Does this command change GPT partition style to something else?

3. I have 2 HDD,

Disk 0- empty (1 TB)
Disk 1- OS and recovery partition etc (1TB)

Can I use clean command on Disk 0 (which is empty) . Will mix and match work?

4.Can I have more than 1 boot partition on GPT partition type?

I do not want to change Disk 1 due to my service warranty conditions.
