Here we are, the first problem after my laptop arrived

hello everyone. Right now my windows 7 doesn't boot, the system said no os is found. I explain.

Yesterday, I post a topic where I asked if it is useful to create a second hard drive partition. And many members told me that I should disable Raid 0 because it is not very useful. So I went to the Bios and As Achilleuse said, I had to choose between ATA and AHCI, and if I choose AHCI, I have to choose between legacy or native ahci. I don't know what do all these mean, which one should I choose?
Also, after disable the raid option, my laptop cannot boot to windows, it said no os found.

If somebody could help me, thanks a lot.

 

if ur system configured raid0 when u received and u disabled then u have to reinstall os...retart ur comp put in alienrespawn disc(if u have 1 , if u dont then put in the os disc), boot from ur cd drive...

 

Hi as Achilleuse said, I now have to choose between ATA and AHCI, and if I choose AHCI, I have to choose between legacy or native ahci. I don't know what do all these mean, which one should I choose
I must choose an option between these so that I could reinstall the os. But I don't know which to choose and what do they mean each.

 

what r u trying to do?? i see u has 2x ssd...if u want to use 1 of ssd as storage.. than choose AHCI legacy...
just let u know ahead of time that after u install the os , ur comp only show 1 ssd..u have to config the secondary ssd in the window..tell me when u done then ill show u step by step...

 

just curious why u unraid them..?remember dont fix it if its not broken

 

Snakeye, he wants to use one as a storage drive for files and the other to install his programs and OS on. This way he can split them if need be down the road

 

yes i figured...thats wat i did for my laptop after unraid...the 2nd ssd wont show up once he boot to the window...just let him know that fisrt so he wont panic...

 

Hi thank you for your answers, in fact one Ssd is for windows programs and all annex programs as mozilla, mcfee, internet... And the other one will be used for games musics and movies. So should I choose ahci legacy so that I can reinstall windows?

 

Both AHCI options will work.

 

Because I want to have 2 different partition and stock different files in different partition. Also I am told that raid 0 for ssd is almost useless.

 

Raid is faster but if One hard drive has major fault It hit both hard drives. Not due to both Hard drive that are both faulty but due to one hard drive faulty and both hard drives are in a C:\ drive setup

Like ram if you have Raid 1 You have both hard drive working 256gb same pictures same config. If one failed You can pull failed hard drive out and run it. On the other hard drive.

It like ram if you have 2x2 ram 4gb if one failed you can pull out the failed ram and run it on 2gb.

 

Why didn't you buy a normal 1 TB SATA disk instead of one 256GB SSD for your games musics and movies?
You would have saved alot of money and gained 750GB storage...

 

that's true. But I prefer use ssd for windows files so that it can boot faster. I want to have ssd+sata disk. but Dell doesn't offer such as a configuration.

 

Let me try and explain why this is happening:

What RAID 0 does is splits the files across two hard drives (or in this case solid state drivers). This means that when saving and loading files it can do it from the two drives at once, resulting in higher speeds.

However, if you then disable the RAID 0, the data on both drives will become useless. This is because all the data is split. So, you need to reinstall your OS and anything else.

 

I've got 2x500GB. And I to want SSD+SATA.

Trade 1 of my 500Gb+cash for 1 of your SSD's?

PM me if interested.

 

Since the laptop is all sata, shouldn't it be native ahci instead of legacy?

 

like mandrake said both will works..i has mine in legacy..

 

Do we really lose a lot of speed by disableing the raid 0 when we have2 ssd?

 

In theory, your speed will drop by about half. Will you notice with SSDs? Probably not.

 

So I can disable Raid 0 without worrying about the problem of speed.

 

No, you won't have to worry about speed. SSDs are faster. Much faster then HDD's. HDD's will benefit more from RAID, where as when you run your OS and programs on an SSD, it will be plenty fast. Your advantage to SSDs also comes in that they are more reliable. If they bounced on the ground your information would still be good. If that happened with an HDD, you may damage the platter, losing your information. How are you enjoying that beast of yours by the way?

 

I love it so much that I want kiss it. Every game I run on it is set to max detail. It is really nice to see high detail games which run flawlessly on the M17x. It is a please for eyes. I don't even overclock it yet.

However the fan is sometime a bit loudly. And sometimes the games get a bit slow during 3-5 minutes, and then become normal. I don't know why.
