How to extend an Extended Partition; leave logical volumes intact

Use the cool new Partition Wizard boot CD Extend feature which allows you to add/subtract from any other partition even if it's not adjacent, plus PW always treats Primary and Logical the same for resizing purposes: How to extend partition easily with Partition Wizard - video help.

Remember that you're only required to keep the OEM partitions if you intend to use the factory image which is a corrupt install to begin with, and which no tech enthusiast would keep. Instead you can make your Recovery disks and then delete all partitions to create new as you wish during a Clean Reinstall - Factory OEM Windows 7.

Thanks. I already made the Lenovo default factory recovery DVDs; it was the first thing I did after the first start up where I set the language, computer name, p/w, etc. And those discs will restore the laptop to its out of the box status, even restoring deleted partitions, for purposes of warranty support. And as I stated, on my first V570 laptop I nuked everything and started from scratch. The thing about that is that it requires having copies of all of the V570 drivers, and some parts (like the Power2Go software) aren't even in the proprietary back up folders. If I can avoid that while at the same time accomplishing what I want, that'd be the best solution.

PW sounds fine, but since I already have Paragon, and am somewhat familiar with how it works, I wanted to know from SIW2 if it could be used to do what I want. If not, I'll certainly check out PW on the CD.

Also, it may be a matter of semantics, but what I want to do is increase the size of the extended partition, not the logical drive already in the extended partition. That's where I think things get a bit tricky. There's no actual drive letter for the extended partition; only "D", the logical drive housed inside. I don't want to change "D" in any way; it messes up the Lenovo routines. That's why I said I'm not particularly savvy when it comes to these fine details. I'm savvy enough to get the major pieces in place when things work well with the software I'm using, but this is a very weird thing because if it weren't, the solution would have been posted a long time ago on the Leonvo community forum.

So you want to shrink the C partition, which is not a problem in DM, and shift the BEGINNING of the Extented partition (dark green encapsulation) towards the left, absorbing all the newly created unallocated space, thereby leaving the D partition untouched.

The answer is in my last post #24, just prior to your first post. Your problem can be solved using GParted, which you can downloaded from:
GParted -- About

Burn a Live CD/USB from it and boot into GParted. You'll see a DM like representation of the partitions of the internal HDD. If you have already shrunk the C partition to 65GB then next is to move the beginning of Extended partition to the left.

In GParted, just click the /dev/sda3 |_| extended line and in the graphical representation on top you'll see a dashed line popping up which encapsulates all that is inside the extended partition (that is, the D logical partition and some unallocated space in your specific case).

Then in the menu go to Partition->Resize/Move and stretch the left side of the extended partition completely to the left, encapsulating all the unallocated space. NOTE, as you are using Win7 the partition alignment goes in steps of 2048 sectors, meaning in blocks of 1MiB assuming sectors of 512 bytes. HENCE that you need to put the option Align to: MiB. Do NOT leave the option on Cylinder (which is the legacy 63 sector alignment prior to Win Vista) or on None. Put the option for sure on MiB!!

Finish the operation by going in the menu Edit->Apply All Operations and you should be set.

Also, prior to doing all this: BACKUP ALL YOUR DATA!!

If you're not sure about the partition alignment scheme that is being used on your HDD, right-click /dev/sda3 |_| extended and show Information. A new Info pane shows up with at the bottom info about the First Sector, Last Sector and Total Sectors. Take the numbers of First Sector and Total Sectors and divide those numbers by 2048: it the outcome is a round figure (integer), then the partition scheme is a 2048-sector partition scheme and the option |Align to| must be set on MiB. If you doubt, copy the numbers into this forum and we'll see.

If you're not comfortable with all this, or are not at all to sure, you can test GParted on an old external Hard Drive of even an USB flash drive. Best is to experiment with an old HDD, which you can buy from any website for a few dollars, put it into an external USB enclosure and you're all set to go for the most entertaining experiments. GPared will definitely see any USB external HDD, if at least, the enclosure has a USB 2.0 port; USB 3.0 ports could be a problem for GParted.

Let us know how it went, ok. I've been using GParted a lot for those kind of operations and it all worked fine.

Thanks Johan. It sounds like this should work. But like I said to gregrocker, IF SIW2 responds and tells me that Paragon 11 will do what I want, I'd prefer to use that program since I already have it burned to a CD and know some of its particulars.

And just to make sure...I just burned an .iso of the latest GParted LIVE onto a CD. Is that the right version to use to boot into the program pre-Windows?

In that case I would shrink C by as much as you want for the new Logical partition, create it using PW CD so you can select Logical, then it will create it as a contiguous Logical partition.

I wish you would have asked here before saving all those useless OEM partitions when doing a Clean Reinstall - Factory OEM Windows 7 as we could have told you that 1) Win7 is driver-complete provided in the installer and via Optional Windows Updates when you enable Automatically deliver drivers via Windows Update (Step 3), and 2) after all rounds of Important and Optional Updates are done, any drivers missing in Device Manager can be found on the Support Downloads webpage for your model PC. Drivers disks and folders are dated as soon as they leave the factory.

If you feel there are some special drivers stored in one of the OEM partitions you can back them up, but all drivers are also stored in C:/Windows?System32/Drivers which can also be backed up to browse into for any missing drivers.

So when ready you can delete and Resize C into all of those useless OEM partitions since you stated you wisely have no plans to go back to the factory image or want it wasting space when you've already made the disks.

Remember to double check the partition alignment in Paragon when shifting front or back of a partition; that is 63-sector alignment (Cylinder in GParted) or 2048-sector alignment (1MiB).

All of that is automated in Partition Wizard. We use the modern automated tools here which work best for Win7.

PW CD has helped here with countless thousands of complicated partitioning operations, making it one of the most valuable tools we use here and propelling it to the top of it's field. It also is the only one besides Disk Mgmt which will not fail during resizing causing data loss.

Supposedly, Lenovo has optimized their drivers to work the best, and they do not recommend using any other drivers. That's not to say they're right, but I only go to their site for updates; I never use the Windows 7 recommended/optional driver updates.

And what you're saying is that PW will then create one new logical drive/partition consisting of the space created by shrinking C INSIDE the extended partition that's currently housing the Lenovo "D" logical drive? After that, can I then split THAT logical drive into 2 -- one 500 GB, and the other 90 GB?

Finally, does PW leave the existing Lenovo "D" logical drive intact?

Excuse me, this is the top site on the web for Clean Reinstall - Factory OEM Windows 7 where we have helped tens of thousands of users get perfect reinstalls without a single complaint.

If you want to live in an imaginary XPired world where drivers are still handled manually that's fine, but don't assume that's how things are done with the first driver-complete OS. Win7 provides the drivers it wants, with few exceptions. Any drivers that might provide better performance will be found on the OEM's Support webpage anyway.

What are you going to do in Win8 where there is no user interaction with drivers which are all handled in the background? These advancements were developed in Win7.

I really don't think it's necessary to cop the attitude you're displaying here. It's really counter productive, okay?
