T450s - How to change boot drive - Driving me buggy!!!

Q: T450s - How to change boot drive - Driving me buggy!!!

I've installed a 256 M.2.Migrated Win10 to it. It will boot fine... if I use the boot menu. BUT... Even though I've changed the drive letter, it insists on using the old 16 GB cache drive (which for some reason was the C drive and had WIn10 on it when I got it).I've changed the 16 GB drive to E:, and the new one to C. Why, why, why does it keep insisting on booting from the now E: drive? I even deleted files off it, now it just gets errors and I have to use the F12 boot menu every time to boot from the C: drive.I've searched for hours... and hours... for a way to change the boot order, but Lenovo seems to have (maliciously) removed that menu from the BIOS. How the heck do I change this? Please?

Preferred Solution: T450s - How to change boot drive - Driving me buggy!!!

I recommend downloading and running DRP. It's a recovery tool that has been proven to recover files that most other programs have no luck with. I've even recovered files from freshly formatted or partitioned drives.

You can download it direct from this link http://goo.gl/v51TwD. (This link will automatically start a download of DRP that you can save to your computer.)


Okay this is driving me nutso - I have checked the RD client on the PC side and there is nothing to turn this off anywhere...

I have a desktop which I always have Num Lock on as it has its own dedicated keypad. The problem is when I Remote Desktop into my laptop my laptop does not have the dedicated keypad the numbers on the keypad portion are actually 1/3rd of the letters on the keyboard (I.E I,O,P would be 7,8,9) when numlock is on. It's fine until I disconnect and I go home...

When I get home I start typing as I normally would but half the letters look like numbers because the Num Lock is still on from when I used Remote Desktop to connect in.

I know the obvoius solution is to turn off Numlock on my PC before I disconnect Remote Desktop from the Laptop but I really just want the Laptop to revert back to its original keyboard state once I disconnect...

Anyone know of a solution? Be kind please.

A:Remote Desktop turns on Laptops Num Lock - Driving me buggy

Have you checked and tried to manipulate your options under the remote desktop connection / local resources?

There is also a registry key that can be set on the laptop to make sure it doesnt turn your numlock on:

Set to 0

Here I am, all excited that my vendor will have T450S laptop for me this quarter!   I buy a dozen and start prepping them.  From the time I opened the first box I was less than thrilled; changes to the Windows 7 setup screens (more prominenet Lenovo Logo, different wallpaper) from the T440s I had most recently used seemed odd.  More to the point, however, was that they were blue-screening on me.   I sent the first one back for re-imaging, thinking it might have been a change to the OS that I made.    And then, this week EVERY machine was bluescreening.  Windows 7.  Windows 10.   Didn't matter.   Right now 3 machines are either at the depot for repair or on their way, and the fourth is going to Level 2 support.   The worst part was that none of the blue screens produced a dump file so I couldn't find out what was going on. What I have stumbled upon, was this: putting a password on the SSD leads to the blue-screen.   I can put it on the system board - no problem.   But the minute it goes on the SSD - blam!   I have let my Level 2 support guy know, as well as my vendor.   Anyone else run into something like this?

Hi, my thinkpad's thinklight doesn't seem to be working after replacing the ssd and reinstalling windows. I have already used System Update and Lenovo Vantage to download the drivers, and even reinstalled the hotkey drivers but it doesn't seem to detect my thinklight. I was previously on a Lenovo Signature Edition before, but something messed up when I was cloning the drive so I just decided to reinstall Windows 10 Pro. I used to have three options when clicking Fn+Spacebar, (dim backlight, high backlight then thinklight) but now I only have the two backlight options. I also tried to use TPFanControl to enable the ThinkLight but it just triggers a 0 battery level warning making the computer shutdown unexpectedly. Any suggestions to get my ThinkLight back?

I have a HP ze5568cl laptop (Windows XP SP2). For a few years we've had trouble with the power connector. We've just wiggled the power cable to keep it connected and lived with the problem. It also gets very hot and the fan runs constantly.

Yesterday when I powered it on there was no power, absolutely nothing. My husband has some electronic knowledge so we took the laptop apart and he soldered the loose part of the power connector. While he was doing that I cleaned the fan (couldn't believe how much dust was in there!)

When we plugged in the power cable the orange light came on so we were excited. When we powered it on all the keyboard lights lit up so we thought we had fixed the problem but.... that's all it did. It went no further except that the fan kicked on.

There is a clicking noise coming from the cd drive about every second with the green light flashing. I suppose it is checking to see if there is a bootable cd in the cd drive. I have attempted to change the boot order by holding F1, then F2 but it still continues to try to read the cd drive. I can't get to the screen that will allow me to change the boot order.

I also put the OS disk in the cd drive, hoping that it would start with the disk but it just clicks. Hubby removed the cover of the cd drive and I could see that the cd is spinning.

There were no problems with this laptop prior to the power problem. It was really working very well especially considering the age of it.

I have company files on my desktop computer's original Western Digital 7200 RPM hard drive. Drive letter C: running Vista 64 bit.

The files are saved on the desktop in a folder, where all the shortcuts, folders and icons are.

I installed a SSD hard drive, and re-installed a fresh Vista 64 bit o/s from scratch. Drive letter D: Everything works fine. Reboots are quicker, no more crashes.

I saved company file folder from WD's C drive onto SSD's D drive.

I reboot, I press F10 into BIOS and move boot sequence around from WD to my SSD and save then exit.

When I get to the desktop screen now off SSD, I look on the SSD hard drive, which is now C: and WD is now D:
I copy folder from WD on D: to SSD on C:

I try to open that folder and there is an error.

When the boot is on WD, I save folder to USB. It works fine.
Havent tried copying from USB to SSD after F10 boot change.
Do I have to disconnect the WD hard drive?

i decided to repartion my hard drive as the gaming system i built was poorly planned. i made the c drive 10 gigs the first time trying to keep things as fast as i could (i heard it helps to have the os loaded on a smaller drive). i tried putting my games on the d drive but over some time, with patches and all, things got messy. it was hard to patch some programs on the d drive for several reasons, but i am digressing.

making a long story longer...i totally wiped the hard drive before i repartioned it. it is a seagate 80 gig 7200rpm and i used seagate install cd to wipe the drive with zeros. i figured this was a good thing to do as i sometimes ran the machine unprotected because some games seem to conflict with my security programs. i feared spyware or other nasty stuff that microsoft's free spyware may have missed, so i wiped it.

i made no changes to the bios or hardware. i partitioned the drive with 2 40 gig drives (or so i thought). i loaded windows xp pro from a full install disk. it took forever for windows to run. when it started i saw a divide by zero error. i proceeded to load board drivers. things speeded up a bit but not like it was before the wipe. i then installed all windows updates and sp2. things seemed ok but it still took a long time to boot up.

at some point in the process, i had a disk error and there were a ton of references to things that seemed to be loaded twice. everything was allegedly fixed by truncating and such.

A:hard drive wipe / buggy xp

Ok .. the easy part first - the advertised drive size is the Unformatted capacity. When a format is applied (NTFS, Ext3, Fat32 ... whatever), some of the drive's capacity is lost to overhead.

I would boot to the XP cd, Press Enter to install Windows. When you get to the screen that asks you which partition to install to, delete all partitions shown, create a new partition (40gb if that is what you want), and let the install routine format it (don't use the quick option). Don't worry about the unpartitioned space ... you can set that up after Windows is loaded through the Disk Manager.

I have a problem, that sometimes, after installing Win XP (SP-1), I find the OS installed to another drive then C:.

The machines I've had this problem with, had one (new, empty) harddisk, and a CD-ROM burner installed. The harddisk was always more then 100GB in size.
Usualy the CD-burner would get E: and the harddisk would get F:
I haven't been able to find out why C: and D: is not available from boot.

But is there an easy way to change the drive-letter, once it's been assigned?

Hellowhat is the difference between cloning and imaging. I searched online and i'm a little confused.but anyway I was wondering if I could image/clone a hard drive?I have an old internal 40 gig HD (my c drive) that i've used msizap on it several times to free up HD space and i boot win xp to it.I have a newer secondary 250 gig internal HD that I want to become the boot drive.I have acronis true image 2010 home version.I DO NOT have the win xp disc (or I don't have the office 2003 discs either). The company who did my last upgrades just did the work for me withoutgiving me the discs.I have a 250 gig external hard drive that i can image/clone the c drive and then in a separate image/clone the larger secondary drive to and then image the c drive to the newer 250 gig internal drive and open the case and switch the wires.does anybody see any problems with that? Should I do it a different way? remember I don't have the disc to install xp if a problemarises. thanks for your time!!

A:change boot drive to a new bigger drive

I have a 250 gig external hard drive that i can image/clone the c drive and then in a separate image/clone the larger secondary drive to and then image the c drive to the newer 250 gig internal drive and open the case and switch the wires.

This is a bit confusing to me, the way it is worded. But if I am reading it correctly, you want to clone your boot drive to a larger drive, then use the larger drive as the boot drive. Using Acronis, you want to use the Disk Clone feature under Deployment. I use an older version of Acronis, and unless things have changed in the newer versions, they tell you after the cloning function, to remove the Old Drive from the machine & make the new drive your primary drive; don't simply switch your data cables. In their terms, imaging is creating a backup (tib) file to be used with their restore function, whereas Clone creates a disk of exactly how your input disk looks. Hope this is of help to you.

How to change the system/boot drive letter in XP

If you break a mirror volume or for some other reason the drive letter of your system and/or boot drive gets changed so that the drive now has the wrong letter (not the one assigned to it when you installed the OS), you'll find that the Disk Manager won't let you change the letter of those drives. This is to protect you from making changes that render the OS unbootable, and you should make those changes only if the drive let gets changed as described above. To do so, you have to edit the registry. Be sure to back it up first.
Log on with an administrative account.

Click Start | Run and type regedt32.exe to open the registry editor.
Navigate to the following key: HKEY_LOCAL_MACHINE\SYSTEM
In the right pane, click MountedDevices.
On the Security menu, click Permissions and ensure that Administrators have full control.
Close regedt32.exe and run regedit.exe. Navigate back to the same registry key.
Locate the drive letter you want to change (such as \DosDevices\C:), right click it and select Rename.
Rename it to the letter you want it to have (such as \DosDevices\D:).
Close regedit.exe and run regedt32.exe again to change the permissions on the key back to Read Only.
You'll need to restart the computer for the change to take effect. Be very careful about renaming drive letters of system/boot drives.

I'm currently running Windows XP with SP2. I've also got 4 Hard drives, 2 Samsung 500GB and 2 Seagate 320GB.

Currently, the computer is booting off one of the Samsungs, to an install of windows on one of the Seagates. The Samsung drive has been playing up, and I was wondering if I could boot off the Seagate with my install of windows, bypassing the samsung entirely.

(I know this was a strange way to install XP, I blame the guy who built the thing)

What I've tried so far (because I'm not sure which one of the 320gb has the install):
- Booting off the Seagates indivudally does NOT work.
- Running the windows install disk (while booting off one or the other of the seagates) to open the recovery console doesn't work either. I can't open the recovery console (not that i've done it before) but the install doesn't seem to find any previous records of windows installs.

Any help would be great.

Thanks in advance,

Hey, I recently bought a new 2 terabyte hard drive to replace my old 80gb, slow, 7 year old, hard drive that i was booting from and formatted it while i was in windows 7 booted from the 80gb hdd. After formatting, it naturally assigned the D letter to it. I loaded up a downloaded windows 7 by virtually mounting it and installed it to the new drive labeled 'New volume (D' and after installing windows 7 on it i booted it up. I saw that it was labelled D still after booting into it and my old drive is still labelled C even though i havent booted its OS. Changing the 2tb to first hdd via bios makes my computer unbootable. Removing the cable to the 80gb hdd also does the same. The windows 7 I have installed on the 2tb hdd is 64bit windows ultiamte and i do not have it on a cd. I have it on both hdd's though and burning this to a disc would b my least preferred option as i do not have any 5gb empty discs laying around. The windows 7 I have on the 80gb hdd is windows 7 ultimate 32-bit. I have that on a disk but do not want to use it on my new hard drive. Any idea on how I can change the 2000tb hdd's drive letter to c from d? I have already freed up c by changing the 80gb drive to f instead of c.

A:Change boot drive from D to C?

The boot problem isn't because the drive letter is D, its because of the way you installed the second version of windows 7. Installing it while the first instance of windows 7 is running likely setup a dual boot situation. Your boot loader is on the 80 gig drive so if its not there windows on the new drive won't boot up. If you post a screen shoot of your disk management screen I should be able to confirm my suspicions. I would make a bootable thumb drive from the ISO and install from that with the 80 gig drive disconnected.

I recently messed up my registry so badly that I had to reinstall Windows XP. I had to download, from MS, the file that creates 6 disks, the first of which would boot from drive A:.

I reinstalled Win. Xp, but on a new physical drive altogether, and, I believe, because I may have had the old (bad) physical C: drive in my machine, the new Win. XP drive became Drive F:

I have taken out my old C: (bad) drive out and replaced it with a previous physical drive which, under the old system, was D:, but now which assumed the letter C:.

So now I have drive C: (data only) and drive F: (boot with operating system) and Drives D: and E: which are DVD and CD RW, respectively.

I have read that the way to correct this problem is to take out the existing C: data drive, and reinstall Win XP on the F: drive, which will then become C: Is this right? If it is, then I would lose all the programs I have installed, and have to reinstall them.

I would like to be able to image my existing F: (boot) drive onto my existing C: (date) drive, remove that C: drive, and reinstall Win XP onto my F: (boot) drive.

Would this actually change the F: to C:? If so, could I then copy, or whatever the term is, the image on to this new C: and thus retain my existing registry and installed programs?

In any event, what I am asking is for a way to get a C: (boot) drive that includes my existing registry and programs.

Hello, My T540s (which just ran out of warranty ...) has a very weird issue : When I try to boot (clicking the power button), the fan starts turning, the keyboard's backlight turns on, but ... a second later (even before the Thinkpad logo shows up), the whole computer crashes and shuts down !Where it gets even more special is that from time to time (1 out of 1000) the computer boots normally, although giving me this warning :Secure Flash Authentification FailedCapsule Data is invalid_ I'm kind of lost right now, really don't know how to get that fixed. My friends think that my motherboard needs to be changed, but I really want to be sure before buying a new one (very expensive). I suspect a bug in the BIOS (recent update failed ?) ... What do you think ? Does anyone have or had the same problem ? Thanks for helping, Best, Sylvain E.K.  PS: Running Win7 64bit

A:T450s random crashes on boot

One possibility: damaged USB port.  This was known to happen on some older T-series laptops.  Bent USB port pins would short power, causing the quick shutdown.
It's not likely in your case (would be 1000 failures out of 1000...) but worth a quick check.

I donno wats wrong but since today morning it shows that in the D drive I have only about 7 GBs of space. I was surprised how it could have filled up overnight (it had about 60 GBs free). Laptop runs Win 7 64 bit. The last 'system change' I remeber doing was running the 'hardware scan' from Lenovo that pops up occasionally - but this was yesterday around afternoon.  Is this an indication of the SSD going to die ? I have taken a full backup. I did a diagnostic using the ThinkPad software that has been installed at factory but it showed no signs of hard drive failure. And I checked with Windows system restore too - that has been disabled long time back.

Ok, I have 4 computer connecting to a file sever. One particular computer is buggy connecting the Z: drive (file server). If I dont access the Z: drive as soon as it boots it will not connect to that drive. It will throw some cannot access error. If you leave the computer idle for a while and come back, it will not be connected.

I figured it was a service that was starting later in the boot process that was killing my access. I cannot figure out what service that would be. If anyone has any advice, please post your comments.

I'm no expert, but I'm thinking on these lines:

2. Format the old drive 0 (the new drive 1).

3. Change the drive lettering on the smaller, new drive 0 (the old drive 1) so that Windows is on the C drive.

4. Boot into your Windows DVD and carry out a Startup Repair to repair the master boot record. You may have to do this three times.

Startup Repair

If my advice is not correct, someone will soon be along to correct it.

I have a 5 year-old PC clone using WIN XP/Home. My boot/system drive was an 80 GB WD ATA labelled C. I installed a 160 GB Seagate ATA and used MaxBlast to clone it to the WD. Then I configured the Seagate as the master/boot drive and the WD as the slave. Now my PC calls the Seagate Drive F and continues to call the WD Drive C. All my programs seem tp be working OK but I would like to call the Seagate Drive C and the WD Drive F. Disk Management will not allow changing the letter of the system/boot drive. How can I get around this?

A:How can I change boot drive letter

Hi agradziel,

It's generally not recommended to change the system partition letter as it can cause serious problems. The most logical way of doing it would be to back up what you want to keep from the Windows installation and format then reinstall which isn't too convenient but will save a few potention headaches....

Or you can read the following link for the alternative method:

Hope that helps

Okay... the situation:

Just installed Win7 on my PC. Formatted my Vista 200gb sata drive C: and installed x64 over it. my other two drives have music files, documents etc on them. I have previously had installations of Ubuntu and the dev version of Win7 that came out some time ago.

Now, after the Win7 installation and the pc restarted I got a GRUB loader error (the boot screen for ubuntu) presumably because I deleted the ubuntu partition. So I changed the boot order to one of the smaller hard drives and Win7 loaded up. So it seems whatever it is that decides what to boot is living on one of the smaller hard drives. I want to switch it over to my main C: drive where the Win7 installation is because I no longer have any other OS on my system. I'd like to keep those drives as seperate removable devices so if windows booting up depends on one of them and I remove it then I'm screwed!

Any ideas how I can change the boot device?

Cheers! P.s. sorry for any incorrect terminology that might not make sense. I just hope you can understand me!

I have purchased a newer and faster (used) desktop style computer for my everyday use. It came with a 500Gb HDD and I quickly upgraded the OS to W10, but I'd like to use a 120 Gb SSD from my older laptop and install it additionally into this new computer and make it my primary boot drive for faster Windows loading and perhaps add a few other regularly used performance applications to increase their operational speed as well. The desktop HDD will them become primarily a large storage area for the least often accessed programs or other files.....or so goes the plan I have in mind.

I have cloned my SSD drive to another mechanical HDD which is now installed in my older laptop, and it's back up and running fine. My question is, can anyone assist me on getting the SSD installed into the desktop as the primary boot drive. Both the desktop mechanical drive and the SSD have the Windows 10 upgrade installed, but the SSD W10 is still registered with MS as being with the laptop device, and of course the desktop W10 is listed with MS as being on that device......how do I get them switched, so to speak?

I have the adapter bracket and connection cable to physically install the SSD internally in the desktop, but I may have to use a USB connection first to get the correct (desktop booting) version of W10 installed into the SSD. I presume I'll also have to delete or disable the desktop's currently installed W10. This is where I need some help. What steps do I have to tak... Read more

I have one drive that has been patitioned into C & D drives. Both had win7 on it however, my C drive was much fuller. I had no way to back up everything so I moved anything I wanted to save from D to C so I can reformt D & reinstall win7. Then I plan to do the same vise-versa, once I have time to sort throught everything. Until then I would like it to boot with D. Keep in mind booth are win 7.

A:How to change boot order from D to C drive.

If you've moved all of the files off of the target partition then boot the installer to Clean Install Windows 7.

As long as you don't touch the data partition but instead select the target partition, Win7 will install there and see itself as C when booted, assigning another letter to data.

Likewise when ready to reinstall to the data partition, move the data off and boot installer to install there. WIn7 will configure a Dual Boot menu and each OS will correctly see itself as C when booted.

Be advised this is not a recommended backup method. It's safer to always have your files backed up externally to another HD, DVD, flash drive, or the cloud such as Skydrive which offers 7gb free storage with each WIndows Live ID also gives you the ability to Sync Any Folder to Your SkyDrive Account | PCWorld.

my storage D drive is now the C Drive and the C Drive is now the storage D drive.

Hey, i'm struggling to work out exactly what the problem is... Does the OS load?

If the OS loads and you want to change which drive the pc boots from then:
- download EasyBCD
- Open it
- Change to the "Change settings" tab
- Change the drive letter
- Click "Save Settings"

If you're just looking to change the drive letters of your partitions then look here:

I recently had to wipe the hard drive of a new computer (Intel mobo, core duo E8400, 500GB Seagate drive) clean because it had developed some problems (like having to reboot after coming out of standby or hibernate), and no system restores or Windows XP repairs did anything. I use a program suggested by J & N computer support, where the custom computer was build. It's called "AEF", which you run from a CD. It destroys the partition on the HD. However, the only option I could find when I ran it was "delall", which deletes all partitions. When I installed Windows, it assigned drive letters to the card readers FIRST, and the HD last. So now my HD is H: and my CD/DVD writer is G: IOW, it assigned the letters in reverse order.

Diskmgmt.msc will not allow you to change the boot drive letter. I would rather not have to destroy the partitions again to get it to make the boot drive C: (how do I do that, anyway when the Windows install disk seems to have a mind of its own?). Is there any commercial software on the market that will allow you to change the boot drive letter?

I have a problem with windows 7 boot drive.

I don't know how but when I installed windows 7 long time ago, I installed it on C drive but somehow the boot file was made on a different drive. If you check the screenshot you can easily understand.

Windows and Primary Drive is C: on Disk 2. But somehow the bootmgr is on Disk 0. I want to remove the Disk 0 from the PC but when i do that i can't Boot pc anymore. How do I set it so the boot file is in C drive on Disk 2.

Please help, I've tried windows recovery start repair but that didn't help!

A:Boot Drive Change - Urgent


First you will need to mark the Windows 7 C: partition as Active in Windows disk management as outlined in Option One of this tutorial at the link below.

I see it's already active, just skip the above step.

Startup Repair - Run 3 Separate Times

Then you will need to power down the PC and disconnect the other HDDs and connect the HDD that is currently Disk 2 to the #1 SATA post of the mobo and set it as the second boot device in the BIOS after the CD/DVD drive.

Then run the 3 separate startup repairs discussed in the main body of the tutorial to create a new set of "System" boot files to the Windows partition to get it booting on its own.

I have a fresh installation of WinXPPro on a new HD wherein I'm in the process of installing programs. I noticed that WinXP arbitrarily assigned the boot drive F: and a USB Drive as C: Ordinarily, I would not consider this a problem, except when I attempted to install a MB driver, it was looking for C:\boot.ini! I have examined the procedure at http://support.microsoft.com/kb/223188, but there is no protocol for recovery in case my PC doesn't boot! So what if I backed up my data? What do I do If it can't boot?

P.S. I found autoexec.bat, config.sys, io.sys, and msdos.sys on my USB drive which tells me something screwy is going on. Please Help! Thanks in advance.

A:How to Safely change my boot drive from F: to C:

You haven't told us how you accomplished this install...how many drives were attached to the system at that time...I will give generic info, which may help you to understand what happened and why.

First...if this system is an OEM (e.g., HP, Lenovo, eMachines, etc.) system and used recovery/restore disks or partitions...the manufacturer of those systems determines what your options are.

Second...if you have an actual MS Genuine XP CD and the system is self/custom-built...and you have an OEM CD...you need to be aware that Windows does a detection/count of all attached drives when it does the install. For every drive other than the optical drive used...and the hard drive to be used...the install routine assigns a letter.

C: is the first letter assigned, then D:, and so on.

If the install routine detects one hard drive and one optical drive...it assigns C: to the hard drive, with D: being assigned the optical drive.

If the install routine detects any other drives...either the install won't complete or it will assign letters to those drives. This includes flash drives, USB-connected external hard drives, and external devices which have been added to the system (such as card readers).

When ready to actually do the install...the routine goes through any letters it has already assigned to detected devices on the system...and then it assigns the next letter to the actual install.

Once this occurs and the boot drive has a drive letter other than C:, the only way that I... Read more

The problem I?ve been having is that after the bios screen I get a black screen with a blinking white cursor. I pop my windows dvd into my drive and change the boot priority to cd rom, thinking I can do a system restore to a previous date.
I have five physical hard drives. 4 1tb drives in a raid system for storage and a 500gb hdd drive to run OS and some games on. What I found out is bios has one of the storage drives having boot priority, but I cannot chose the hdd drive that the is works on.
After start up I press F8 and it gives me a larger list of drives to boot from, including the hdd drive, so I am able to boot up that way without issues. But do not know how to make this the priority drive is bios.
Any help with this would be greatly appreciated.

I have a Dell Inspiron 7720 Win 8 x64 PC which includes UEFI (described in Microsoft link below). However, UEFI is accessed on Win 8 from Settings Charm > "Change PC Settings". This requires that you have booted the system already. In case of a main disk crash, you need to boot from another drive, like a thumb drive.

During restart my Dell PC displays "F12 Boot Options" in lower right of screen during restart, but multiple presses of F12 during startup are ignored. Likewise when I try F1 or F2 during startup. So I have no way to specify an alternate boot drive.

I am thinking maybe my PC is defective, but also maybe I'm missing something.

Any suggestions greatly appreciated. Thanks.

I've got a clientt's Gateway computer with the following drives:
A: floppy
E: DVD/CD Writer
F: USB Harddrive
G: Some Removable Drive

The Goal was to replace the current C: drive with a new hard drive (H.

1) I did a full restore from the client's latest backup to the new drive.
2) I swapped the drives (C: is now the slave and H: is master)
3) I booted successfully into the H: drive.

What I wanted to do is change the H: to be the C: drive. So I deleted the page file and renamed the C: to I: and rebooted.....OOPS. I guess that the H: was still pointing to the C: for files/information.

Is there any way to change the I: back to C:?

My year-and-a-half old T450s stopped booting up. Yesterday I was prompted for a Windows update and restarted the machine, as usual. After the update, I'm able to turn it on but it wont boot up. It shows the initial screen, with the "Lenovo" logo and won't proceed beyond.I tried taking out one battery and then holding the on/off button for 30 seconds, and also the emergency reset on the bottom, but neither changed anything. It simply won't go beyond the initial screen. Does anyone have any thoughts? Thanks in advance.   

A:ThinkPad T450s won't boot up after a Windows updat...

I think you are experiencing the same issue I have. If you notice after the Lenovo boot logo the display still stays on its just black, what it appears to be for me is a video failure after trying to update to windows 10 anniversary update. Try plugging in an external monitor and see if you get display, I did in my case.  Remove your hard drive and restart the PC, this should get the bios working again, go into your bios and disable secure boot so you can boot to a USB. Create a bootable USB 3.0 using a USB3.0 drive (formatted to NTFS) from Microsoft's site - https://www.microsoft.com/en-us/software-download/windows10/ Then goto repair my computer and choose rollback update, this will get you running again.  I have a p50 with Nvidia M1000M dedicated graphics, so I am still trying to figure out if this is a driver issue.
