Hello.
(Sorry about my English, it is bad
)
I have bought new Acer Aspire E 15, E5-511-P461
S/N [edited for privacy]
Then I installed to him SSD drive, Intel SSD 530.
And when I try to instal win 8.1 x64 on it - windows installer does not see any HDD. He suggest me to load driver..
I have tried any drivers.. From intel SATA/RAID/AHCI.. - doesnt work.
In bios SSD drive - is detected! And thru USB -> SATA converter from windows it is work OK!
In bios is AHCI mode selected.
I try UEFI and Legacy modes - doesnt matter
Then I try to install it on my OLD Aspire 5738ZG. I put Intel SSD 530 to it, choose SATA AHCI in bios, then put same windows 8.1 install cd and it see it! I can install windows!
Then I try to put Win7 x64 to my E 15, and its see it! It see SSD!
So, I made a conclusion Acer E5-511P has no compatibility with installation Win 8.1 on SSD drive! It does not see it!
And it is not hardware problem, because BIOS see it, and Win7 installation CD - SEE IT !
So, it is software problem, may be in BIOS ?
I have send an email to acer - no any answer.
I hope specialists from ACER.COM read this forum, or this forum read people who can contact to acer workers 
It will be veeeeery GOOD !
Realy.
Really need to solve that problem!
All advices from all people are welcome!
PS Have tried initialize it from Windows disk management, initialized OK, formated OK, but still not see from win 8.1 installation setup..
