Ghost CD-rom pop up

[HadronMI]

Hi!

I have a Redmi 1S WCDMA version (V47,MultiLanguage).I had some problems with apps,and i had to flash fastboot rom V47 Global.I succesfully made it,but now when i plug it to my PC (Windows 7) ,a Xiaomi CD-ROM apper in the MyComputer folder.Before the flash,i never saw that install file,and its fully chinese (i dont speak chinese )I would like to remove it,and make the phone like before the flash.This CD-ROM pop-up really annoying.I found in the "en.miui.com" forum,I have to root the phone,find the /data/miui/cdrom_install.iso file and delete it.I did it.But if i plug the phone to the PC,still pop up a CD-ROM too,without any Xiaomi install file.Just a CD-Rom what i cant open.I think still have some files,on my phone.Is there any fastboot rom,without this feature?Or can i delete it for ever?Can someone help me?

Now i can see (and i want to delete) this F drive:

there are a iso file in the rom, maybe if you remove it with a root explorer it will remove the cdrom ? not sure if it will not break things..
oops i din't read

Yes,i did the same.Deleted the iso,but the phone still emulate the CD-rom... So there are files,still somewhere.I dont know what i have to delete too...
