System Reserved Partition & RapidBoot

2011-06-26, 15:53 PM

I just recently swapped my HDD with a SSD (on a W520) and installed a fresh copy of Windows 7 Ultimate x64 instead of recovering with the 'supplied' Lenovo Recovery DVDs.

I saw on the old HDD that the Lenovo installation had made a 1GB System Reserved Parttion which was half full. There was also a folder named RapidBoot.

 

Now, is there any reason why Lenovo created a 1GB Partition? Is it needed for e.g. RapidBoot? 

After manually installing RapidBoot, my boot time was worse so I ended up uninstalling RapidBoot. Does RapidBoot need a couple of starts to figure out, how to boot faster?

 

Thanks in advance,

Beto

The 1GB partition is the active partition (on standard HDD), so it is necessary to enable rapidBoot. edit: EE

 

I can only speculate on this but- i doubt that RapidBoot (EE) "learns" how to boot your machine on the go. all it does is prioritize which processes and drivers start first to give the illusion of a faster boot (the other processes still have to start behind the scenes).

 

If you do a clean UEFI install on SSD, you won't be able to get faster boot times than that. alternatively you can do a factory install with the rapidBoot (system) partition. recovering the 1GB system partition only and doing a clean install on a second partition is not really an elegant solution, one that i would call ad hoc..

Thank You for Your input.

 

Well, I think I'll leave it with the fresh Windows install. I just got fooled by the '7 to 10 sec. boot time with RapidBoot' which I'm not getting close.

The System Reserved partition and RapidBoot are completely unrelated.

 

In a lenovo preload, the system reserved partition is approx 1GB.  In addition to some critical Win7 boot files, this partition also contains the Lenovo Rescue Environment (WinRE) which starts the factory restore process.  If you install Rescue and Recovery, the Rescue and Recovery environment (WinPE) is also installed to this partition.

 

In a clean Win7 install, the system reserved partition is approx 100MB and only contains some critical Win7 boot files and a basic Win7 Rescue Environment.  If you install Rescue and Recovery, the Rescue and Recovery environment gets installed to the primary partition (C:) because there isn't enough room on the 100MB System Reserved partition.

 

RapidBoot is software that tries to make your system boot faster by delaying unnecessary drivers and services until after the system is fully booted.  It is optimized to work on a Lenovo preload.  If you install it on a non-preloaded system and it makes your boot time slower, then you should uninstall it.  It does not "learn" how to boot faster over time - it will either work or it won't.

Thank You for Your answer!

 

What does "Lenovo preload" mean? I thought that every Laptop which is certified as/with "lenovo ENHANCED EXPERIENCE 2.0" could take advantage of RapidBoot. I've never seen the W520 advertised with RapidBoot as a special feature, but it has EE 2.0

 

Anyway, I'll need to take my stopwatch again to make further tests :)

A lenovo preload is how the machine is setup from the factory. a factory recovery will revert your machine to the lenovo preload state; as opposed to a clean install of windows which is not a preloaded setup.

 

'Enhanced experience' is only a marketing name- just like "Rapid Boot". afaict EE 2.0 is the current marketing name for their "tweaks", which require the active 1GB partition for certain boot files. tbh some users (see forums) don't see any difference in boot time and have reported that, and as i've said previously, a clean UEFI install on a SSD will also be very fast.

 

Of course lenovo will stand by their name and EE. it will most likely improve boot time by a few seconds, perhaps shut downs also, but you have reason to be sceptical about 7 sec boot times in real world situations.

in a clean install of win7, the 100MB active partition is only present on a SSD and has nothing to do with lenovo. a clean install on a standard HDD has no such partition.

I did some testing:

'login' = time when the Windows login screen passed(no password).

'loaded' = the circle on the cursor disappeared, regardless of the System Tray Icon still loading applications.

Specs: W520 (2720QM, 12GB RAM, 1000M, 128GB crucial M4 SSD), Win7 Ultimate x64, MS Office, VS2010, SQL08, MS Security Essentials, Dropbox, Adobe Reader

 

1. Boot:   login: 33s   loaded: 37s
2. Boot:   login: 31s   loaded:37s


1. RapidBoot:   login: 32s   loaded: 38s
2. RapidBoot:   login: 39s   loaded: 45s
3. RapidBoot:   login: 40s   loaded: 45s

 

So, no RapidBoot for me then...

If you have a solid state hard drive, Rapidboot cannot speed up your boot time.  The only thing that rapidboot does is change the start order of applications in a manner that wll allow for a traditional hard drive to avoid additional seek time and start up faster.  Since solid state drives effectively have 0 seek times, there is nothing rapidboot can do to make the startup faster.  I wouldn't install it - it is just one more piece of software that can go wrong.  Microsoft spends enough time engineering startup times - I don't want another vendor messing with my OS.

Not in my experience.  The clean Win 7 installs I've done on  HDs have all included the 100MB partition.

 

Perhaps I misunderstand.  Can you clarify, please?
