I tried the same one this morning and it worked . No idea why and how but it did .I didn't perform any changes other than creating the RAID configuration from scratch   Thx. 
Hi  I'm trying to install windows server 2019 standard edition on my new PowerEdge R740 but after I select the language I get a blue screen saying IRQL_NOT_ OR_ LESS_ EQUAL ( Attached ) .  The weird thing is I have tried and succeed to install Windows server 2019 on this server a few days ago ( Probably a different build ) . Maybe it is something related to hardware compatibility with the build I'm trying to install now .(I couldn't use the previous installed build due to licensing stuff) . Now I have build that is specific for PowerEdge DELL EMC (Windows server 2019 products (16 cores) RESSELER OPTION KIT . I performed hardware diagnostics which didn't raise any issues . I couldn't perform any firmware updates as I don't have OS installed and this server can not be connected to the network .  Anything else I can do ?  [IMAGE] Thx .
